This issue could have several causes:
Embedded Content (iframes)
The most common cause of undetected Google Fonts is an external resource, which is embedded in an iframe, is loading the Google Fonts. Read this for more information on why OMGF (or anything) isn’t capable of detecting those Google Fonts.
CSS Optimization and Page Caching Plugins
The most common cause is that you’re using a CSS
minification/combination plugin that also has an option to optimize Google Fonts, e.g. Autoptimize, WP Rocket or Asset Cleanup.
While OMGF is extensively tested with most popular optimization plugins, try disabling that option. OMGF (Pro) does it better anyway and it might be interfering with OMGF (Pro). Make sure to flush the plugin’s cache after changing the setting.
Cookie Notice/Consent Plugins
Another common cause is that you’re using a cookie consent plugin which blocking the loading of Google Fonts until prior consent is given. Before running OMGF (Pro)’s optmizations, make sure you’ve removed Google Fonts from your cookie consent framework/plugin.
Staging Areas
If you’re running OMGF (Pro) on a staging area, which is locked to the outside world by e.g. basic authentication or a splash screen (i.e. an Under Construction screen), this needs to disabled temporarily in order for OMGF (Pro) to run. This the detection script runs at server level (and not in a browser) it can’t “act” like an administrator and get access to your site’s frontend.
File/Folder Permissions
Default WordPress instances have folder permissions set to 755 and file permissions to 644. If somehow in your case this is different, it might be that OMGF (Pro) isn’t able to write files to the folder defined under Advanced Settings (default:
/uploads/omgf ).
Unconventional (or Exotic) Google Fonts implementations
Due to coding standards/restrictions in the wordpress.org repository, OMGF is restricted to scanning the HTML document for Google Fonts. If your theme and/or plugins are using exotic implementations of Google Fonts, an upgrade to OMGF Pro might help you out. Click
here to purchase OMGF Pro.
OMGF Pro detects Google Fonts loaded in:
- inline @import and @font-face statements,
- @import and @font-face statements in local stylesheets,
- WebFont Loader,
- Early Access (Beta).
Already a Pro user and still no luck? Then open up your browser’s Developer Console (opens by pressing F12) and/or your server’s PHP logs. Look for any errors related to OMGF Pro (or other Fatal Errors) and continue further down this FAQ.
