Hello,

There is a server-side permission problem. Using below 2 ways, you can solve it.
1) give 755 or 777 folder permission to "/var/cache/dev/smarty/compile/"
2) if the result will be the same, contact host providers, they will do best all of them

ok i will check with hosting provider, thank you

by the way is it normal that when i delete all folders under /var/cache they will appear again even without cache running?

[MigrationPro]

if you have enabled cache of the PS it automatically collected.
 

Also, you can't keep this folder clear. Eventually, PS will collect a cache of the system module or theme.

cache is not enabled but a lot of folders and files are created by ps by itself is it ok? (i mean about 3-400Mb for day in /var/cache/
