Many “plugin won’t install” or “upload failed” problems are a PHP limit. The site’s PHP tab lets you change those limits yourself and switch the optional PHP modules your site needs.

Changes are applied within a few seconds and your sites keep serving while it happens.
What’s in this guide
PHP settings for one site
Open the site’s page → PHP tab. You can set:
- Memory limit
- Max execution time
- Max upload file size
- Max POST size
- Max input vars
- Max input time
These apply to that site only. Leave a box empty to keep the platform default; each value can go up to what your plan allows, which the tab shows beside it. Back to platform defaults undoes everything in one click.
PHP modules
The tab also lists the optional modules for the PHP version the site runs on, with a switch for each, and the modules that are always included. A module is loaded by the PHP service itself, so switching one on or off applies to every site of yours on that PHP version on that server. If your plan does not include module management, the tab says so.
Changing the PHP version
The PHP version itself is changed with Edit on the site’s page – see the article linked below.
