Hi, It seems they also have difficulty to access files, is the theme allow only for FTP access? does the theme needs more than 750MB?
They wrote to me:
First of all, our system administrator noticed that you have a a custom hosting with 750 MB of space but 751 of it are used, so we recommend you to buy more space.
In default settings, WP installations on our servers do have direct access to filesystem. If your plugin/theme detects that only FTP access is available for some reason, it is most probably due to changes you or your theme/plugin did, that made WP to switch to next available access method. Unfortunately, we don’t know much about how WP does this detection, so can’t give specific advice to you.
