Your site runs on a current, supported version of PHP, and the server's default limits suit almost every site. If an application asks for a higher limit, you can set an override yourself under Account Manager → PHP Settings.
Under Add New Override, pick the Setting, choose or type the Value, and click Add. The change applies to your whole site within a minute or so; no restart is needed. Overrides you have added are listed on the same page, where you can change or remove them. The ones people actually need are:
| Setting | What it does | Typical value |
|---|---|---|
| upload_max_filesize | Largest single file you can upload through your site, e.g. in the WordPress media library | 64M |
| post_max_size | Largest form submission; must be at least as big as upload_max_filesize | 64M |
| memory_limit | Memory a single page load may use; raise if you see "Allowed memory size exhausted" | 256M |
| max_execution_time | Seconds a script may run before it is stopped; raise for slow imports | 120 |
| max_input_vars | Number of form fields a page may submit; raise if a large menu or theme settings page will not save | 3000 |
| display_errors | Shows PHP errors on the page; turn On only while diagnosing a problem, and Off again afterwards | Off |
If an application says it needs a different PHP version, raise a ticket and we will advise; the server currently offers one version, kept up to date, so this is rarely an issue.
If you have any trouble, raise a ticket and we will sort it out.
