I moved my site to the other host and got a troubles in administration panel. Top menu is inactive, any button does not work.
The other problem - I can not update my version 3.8.6 to 3.8.7. The package gets to the tmp directory and progress bar are shown but nothing else.
What I have did:
-$log_path and $tmp_path are tuned
-Rights on directories and files are 755 and 644(media, images, tmp, cache...777).
-Files and database was removed few times but problems are not dissapeared
