Why does not the selection of categories in CMS DLE?

When adding a news frame in the category field, open the list window and instead of selecting by clicking on a category it is simply removed from the list. Thus it is possible to clear the whole list and nothing to select. The news is saved, but without a category. You can manually fix (in the post table via phpMyAdmin ) and then it works.

The categories in the list are not lost. Tried export-cleanup-import the table. The thanks button "Clear cache"and delete files from the directory cache.

Version DataLife Engine: 9.6
Operating system: Linux 4.4.0-133-generic
PHP version: 5.2.17
MySQL Version: 5.6.25-73.1 MySQLi

Ideally upgrade to the latest version and everything should get better, although more like a problem with js this can be seen using the developer tools(console)
When you select a field in the console gives:
TypeError: c.lastIndexOf is not a function

And early swears the deprecated methods
getAttributeNode(), getPreventDefault()

ps considering to move it to wordpress.. - Keagan.Hilpert commented on March 23rd 20 at 19:23
@Keagan.Hilpert, you just have to see in what file. and try to replace it with the original backup, or is it a conflict with another script - Verdie_Doyle commented on March 23rd 20 at 19:26
