 * Hi,
 * I get this warning at the top of page.
 * Warning: file_get_contents(//fonts.googleapis.com/css?family=Open+Sans:300,300italic,
   600,600italic): failed to open stream: No such file or directory in
    ~/wp-content/
   plugins/hummingbird-performance/core/modules/minify/class-minify-group.php
 * It started sometime a couple of months ago. If I turned off Enable advanced mode
   it didn’t show up until recently but now it always stays at the top no matter
   what. How can I make it disappear?

 * Hello [@sailors](https://wordpress.org/support/users/sailors/)
 * I hope you’re well today!
 * Could you please try this:
 * 1) clear cache on site
    2) got to Hummingbird -> Asset Optimization page and 
   re-check files (that shouldn’t change configuration unless there were significant
   changes made on site; e.g. new plugins added or some plugins removed in which
   case Asset Optimization should be configured again anyway) 3) make sure that 
   you’re in “advanced mode” and look for any references to Google Fonts or Google
   Fonts CSS on the asset list – if you still see them there, make sure that they
   are not set to be compressed, combined, moved to footer and/or inline 4) save
   changes and clear cache again (just in case)
 * Let us know if that helped or if the warning is still there after that, please.
 * Kind regards,
    Adam

 * Thank you for your advice, Adam. That solved my issue. It appears every time 
   I update my installed plugins, hope I don’t need to do that process, though.
