UMI CMS is positioned as a “new generation website management system”. The official site welcomes us with a joyful message that more than 86,000 licenses have been issued, but it is worth noting that all types of licenses are considered here, not only paid, but also free. So, for example, I needed to get more than a dozen free licenses, and since all licenses are tied to a domain, then when transferring sites to working domains, you need to get the license again. On the main page of the official site it is written that UMI CMS use more than 10,000 sites and lists the major sites that use this system. The first site on this list is the Skolkovo site, which has already left UMI.CMS on ASP (this has already been written about. It is the same with the Moscow Government website , although on the official UMI.CMS website it is indicated that they work on this particular CMS.Well at least that the site is not imposed tables, such as the official site of CMS DLE . The Website Developer Website and UMI.CMS Developer leadconcept(.)com/custom-content-management-system.html Website are not made on UMI CMS, but on the basis of simple HTML pages using frames (by the way, on all pages the title of the document is not registered in the layout). The wiki site is also not made on UMI.CMS, but on the open source MediaWiki engine. To install UMI CMS on your hosting you need to download the install.php file, which will download all the CMS files from the Internet. Accordingly, it will not be possible to have UMI backups in different versions, since the latest version is always downloaded. It should be noted that UMI CMS requires the presence on the server of the expansion php xsl, which is not installed on all hosting. A full trial version of UMI CMS without demo sites installed occupies 180 MB (4 985 files and 1 277 folders), the database consists of 80 tables with a size of 3.5 MB. Verification by the validator of the UMI CMS admin part produces 36 errors and 3 warnings (no document type has been declared, there are no alt tags for images, non-standard attributes). When editing materials in UMI CMS, there is no simple “Preview” button, but there are three “Save” buttons: Adding images (known CMS problem) turns into hell if the number of images becomes more than 20-50, because after loading an image, you must first find it (by name or thumbnail), select it and insert it. Those. no simple mode - chose file, uploaded, pasted. Layout One of the main advantages in the opinion of the creators of UMI CMS is the edit-in-place edit mode, which allows you to edit the site in visual mode immediately on the page without entering the admin area. The reverse side of this feature is the use of non-standard attributes for html tags (for example: umi: element-id = "44" umi: region = "row" umi: field-name = "name" umi: empty = "Section name" umi: delete = "Delete" ), as a result of which a non-valid layout is obtained. UMI CMS uses macros that trigger certain actions (for example, showing a catalog item, photo galleries, etc.). When these macros are inserted into the visual editor (using Tinymce), they are wrapped with p tags. As a result, when most macros are triggered, div tags appear inside the p tag, resulting in a non-valid layout.SEO UMI CMS has certificates “Optimal for SEO” and “UMI CMS meets the requirements of SEO” . In the SEO settings leadconcept(.)com/seo-services-company-california.html you can specify a prefix for the Title tag, although it is better to specify the suffix, rather than the prefix. Automatic generation of description and keywords tags is also not supported. By default, CNC cannot be created using addresses like system modules (for example, news, catalog, etc.), as a result pages with the names news1, catalog 1 appear on the site (although there is a possibility to include support for such CNC, but the documentation strongly recommends not to do this). The CNC in UMI.CMS is generated automatically, but by default, an underscore "_" is used as separators between words, although the recommended sign is a hyphen "-" (the ability to enable the use of a hyphen is, but it is hidden very deeply and is configured in config.ini ). The latest versions of UMI.CMS have built-in support for the MegaIndex service and in the settings of the SEO module you can specify your account details for this service. By default, there are data from UMI - login and password, hidden behind asterisks. This password can be easily overlooked (for example, through the Web Developer extension for Firefox). Updates Updates sore theme of many CMS. In UMI CMS, for example, when upgrading an old version to a new one, some modules that were previously in the current edition of the system, i.e. In addition to paid updates (and paid updates), you will need to pay extra for the modules missing during the update. There were also cases that in the new version there are new errors that were not in previous versions, and the tech support itself recommends restoring the site from a backup made before the upgrade. Development The system files are in the classes folder, most functions and classes are not documented in any way (there are comments only in 82 files out of 786), i.e. deep understanding of UMI CMS without spending a lot of time will not succeed. All your additional functions in UMI CMS should be written in custom.php files, which should be placed in the system folders. Over time, the custom.php file grows with its functions, respectively, there are problems with enabling / disabling individual functions, transferring them between projects. Additional functionality (paid or free) for UMI CMS is available very little. Of the additional paid modules there is only the GeoIP module , some projects are on the UMI HUB, all missing functionality should be written independently. Errors Errors and glitches are different, one of the most amusing - change tags b to strong - you get not working macros after the place where the tags are replaced. One of the last mistakes I encountered today. Install the UMI.CMS or use the demo version , set it in the admin using one of any templates (xslt or tpl), then go to edit this template and delete all the information about it (name, file address, etc.) As a result, we get the error: Despite the fact that the template for the user part of the site was changed, the admin panel of the site also stopped working. If you want to have this system as the "heart of your site", then I remind you that the most complete edition of UMI CMS costs 29,900 rubles. The most discussion in the comments was caused by security issues, in particular the lack of processing of the output of standard fields of materials in tpl templates. The representative of UMI CMS flatly refuses to recognize this as a vulnerability or potential vulnerability, calling it a “flaw”. He also unequivocally blames UMI CMS for the developers of the site for such “shortcomings” of UMI CMS. Everyone will make conclusions for himself.
