FAQ

Builder requires FTP passive mode enabled on your server to be able to publish websites. Please refer this topic to enable FTP passive mode on Plesk:
https://docs.plesk.com/en-US/obsidian/administrator-guide/server-administration/plesk-for-linux-configuring-passive-ftp-mode.74643/.

The problem should be solved with plugin update (update instruction).

Site.pro provides plugin for Plesk 12 and higher (Plesk Onyx, Plesk Obsidian and higher). See installation instruction.

To solve this problem please re-install the plugin on your Plesk server downloading new plugin from your license which you use on Site.pro. It will return back your icon and title and the plugin overwriting should never happen again.
Please note that this action is absolutely safe — it will not affect clients websites.

This problem can appear when using brand of On-Premises type and having builder installed on your server.

• The problem can be caused by builder plugin on Plesk having wrong builder domain saved inside it and therefore when calling it — plugin throws error 404 not found. To fix the problem, update plugin on Plesk (installation instruction).
• If (1) does not help then check the IP address which your builder domain is resolved to on your Plesk server. Try running the following command on Plesk server terminal:
  # curl http://[builder-domain]/api/status
  (where replace "[builder-domain]" with a real domain of your builder installation).
  If you do not get response {"ok":true} then it means that locally Plesk makes call to a different place, and not to builder. In this case check file "/etc/hosts" whether you have hardcoded IP for builder domain specified. If yes, try to remove it (or temporarily comment) and check if builder starts working.

To fix this problem, enable PHP for that particular website (or in its used service plan).
