No, I just changed passwords, paths and other required fields.
I think that problem is with incorrect upgrading. Because after pushing the button “Upgrade” I received just blank screen. So, I changed Off to On and such monster website appeared.
Actually, I do not understand the moment “Synchronize new changes from config.TEMPLATE.inc.php to config.inc.php” from instruction. What I have to do with config.TEMPLATE.inc.php? I just left it unchanged.
UPD. I also see that my CSS is not working anymore.
UPD 2. On smartphone, the menu subitems of “About” (i.e. Editoral Team and other) are inactive. I can access them only after long holding → open in new window / open.
I checked config.inc file and there were really missed fields in character configuration. I set them to UTF-8, so now website looks good and Metadata work well. But: 1) CSS still does not work; 2) Issue with smartphones/tablets is the same.
Do I need to duplicate all preferences from config.inc to config.TEMPLATE.config, or have I leave the last file unchanged?
