 * I had to deactivate the plugin as offer updating Google dropped my entire site
   from index due to 5XX crawl errors. I checked my server log and had thousands
   of errors that begin like this:
   Got error ‘PHP message: PHP Fatal error: Uncaught
   Error: Call to undefined function omgf_init() in /home/77241-60138.cloudwaysapps.
   c…………Deactivating fixed the issue. I updated last night, so I suspect it was 
   something with the latest version.

 * Hi!
 * Are you using opcache by any chance? The latest update included major refactors
   to decrease code execution time by ~30%, and yes, the function `0 `omgf_init()`
   doesn’t exist anymore.
 * So, the fact that your server is still trying to call it, must mean that there’s
   a cache layer somewhere.
 * Not always needed, but always good practice, is to flush these caches before 
   an update, just in case function- or classnames have changed. It doesn’t happen
   often, but in this case, it did. 🙂
 * Let me know how it went!
