Have been off for a while and while checking again seems like i can not upload any file in file manager plus occasionally modules say they are not installed. Literally they uninstall them selves. Dont ask me which site i have tested on all my sites on different servers and they are all having this isue. Please fix ASAP
I hate politics, people who do not make an effort with people and those who try hard to be cool
I recommend to use the FTP Client instead because is safer and faster than use the file upload manager. Also uCoz has a known issue related to the last version of Chromium based browser (some forms doesn't work with the last update of chrome) so you have to use Firefox in order to keep editing or adding entries to you site.
There are several FTP clients but one of the most used is Filezilla because it was released under GPL open source and is actively updated by a big community.
Remember that this is only a forum if you want to make a formal complaint you have to write to the support team via the Control Panel or go to https://forum.ucoz.com/forum/3-14706-1 and there you can report the problem with your server and check the status.
