System Info

A check of your server and your WordPress setup against what Foxiz needs. Foxiz runs on nearly any server, so you only act on a row in red: the reason is written under it.

On a new site, Object Cache is the row most likely to be red, because the switch that clears it is off by default. Your site still works: see Object Cache below for the fix.

Where: Foxiz > System Info.

The page is there before the site is activated too, so you can check a server before you register.

The top of System Info: the System Information title, the line about red values, and the PHP Information rows below it

PHP Information​

Your server's PHP values. A value in green is fine. A value in red has its warning under it.

The PHP Information rows: PHP Version, Memory Limit, Max Input Vars, Post Max Size, Max Upload Size and ZipArchive Support in green, Object Cache in red with its warning under it

  • PHP Version: the PHP version your site runs on.
    • Recommended: 8.0 or newer.
    • In red: Foxiz needs a newer PHP. Ask your host to upgrade it.
  • Memory Limit: how much memory one PHP request may use.
    • Recommended: 64 MB or more.
    • In red: the theme may not work. Raise memory_limit.
  • Max Input Vars: how many fields one form may send.
    • Recommended: 3000 or more. It turns red below 2000.
    • In red: large Theme Options panels may not save completely. Raise max_input_vars.
  • Post Max Size: the largest form submission, uploads included.
    • Recommended: 32M or more. A value of 0 means no limit, and passes.
    • In red: raise post_max_size.
  • Max Upload Size: the largest file you can upload. It is the lower of upload_max_filesize and post_max_size.
    • Recommended: 32 MB or more.
    • In red: raise both values, because the lower one wins.
  • ZipArchive Support: whether PHP can open zip files. Yes or No.
    • Recommended: Yes.
    • In red: automatic theme updates may not work. Ask your host to enable the PHP zip extension.
  • Object Cache: where Foxiz counts requests for its rate limits, which cap how many requests one IP address can make per minute.
    • The value is one of:
      • APCu.
      • Redis / Memcached.
      • Database (transients): no fast cache, and Transient Fallback is on.
      • None.
    • In red only on None: the rate limits do nothing. Nothing else on the site depends on this row.
    • For most sites: turn on Transient Fallback in Theme Options > Performance, in the Rate Limits group. It counts in the database instead, which costs a little speed. If your host offers Redis or Memcached, asking them to turn it on is the faster fix.

The same PHP rows show at the bottom of Foxiz > Dashboard.

To change a PHP value, see Configuring Server Settings. If your host does not let you, ask them.

WordPress Info​

Your WordPress setup and the theme you run.

The WordPress Info rows: WordPress Version, Debug Mode, Debug Log, Theme Name, Theme Version and Get Foxiz with its Plans and pricing link

  • WordPress Version: the WordPress version installed.
  • Debug Mode: Enabled or Disabled.
    • Recommended: Disabled on a live site.
    • In red: PHP error details may show to your visitors. Set WP_DEBUG to false in wp-config.php when you finish testing.
  • Debug Log: whether WordPress writes errors to a log file. Enabled or Disabled. It never turns red.
  • Theme Name: the theme your site runs. With a child theme it still reads Foxiz, the parent.
  • Theme Version: the Foxiz version installed.
