 * Hi there!
 * I´m having a hard time with the plugin. The first time i´ve configurated a feed
   for Google Shopping it went allright.
    Now I´m trying to configure another google
   shopping feed for one of my vendors (i´m using Product Vendors for woocommerce),
   and I keep getting this fatal error. The steps i´m following are the usuarl..
   category mapping and field mapping. In GTIN and MPN i´m using de wooosea fields
   although the products doesn´t have these codes but I don´t think that´s the problem.
   I tried to fix this by updating the WordPress version to latest (5.4.2) and the
   problem persist.
 * Any idea of how to fix this?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffatal-error-3573%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi,
 * Thanks for using our plugin and reaching out to us. Sorry to hear you are experiencing
   issue with it.
 * Could you show me the ‘fatal error’ you are getting and when are you getting 
   this? Straight after the field mapping page?

 * The error appears after y click Generate Product Feed (Conversion & Google Analytics–
   Last step).
 * In this link you will see the error message I´m getting
    (Translation: There 
   has been a critical error in your website. Please, check admin mail panel for
   further instructions. I´ve sent this to my web developer admin and he says that
   he didn´t recieved any email.) (In the picture you will alse see that WordPress
   5.4.2 is available, I´ve already installed it and the same thing is happening).

 * That is not a very descriptive critical error unfortunately. Did you check your
   WooCommerce fatal error logs of **today** to see if there is a better error description
   in there?

 * I´ve checked actually but the fatal errors doesen´t seem to have to do with Product
   Feed Pro:

   right now. What should I do?

 * Hi,
 * When there is nothing in the WooCommerce fatal error logs then the 500 server
   error could be caused by a firewall or something like cloudflare. Are you running
   such a firewall/caching plugin?

 * This may be a partial installation. I’d try uploading the plugin again using 
   FTP.

 * Hi!
 * I´ve tried everything:
    1) Deactivate and reactivate the plugin 2) Delete the
   plugin and install it again 3) Deactivating WP Fastest Cache plugin 4) Uploading
   the plugin using FTP. Unfourtunately, nothing works. Perhaps this has something
   to do with PHP version / activating or deactivating any PHP extension?

 * `woosync-premium` implies you should contact the author of that plugin directly
   and give them access to your system to resolve the issue.
 * Rather than a partial installation, this may be a partial uninstallation, or 
   there’s something in your theme that still references the missing function.

 * Forgot to tell you, woosync-premium has already been uninstalled and the problem
   persist. I don´t think it has something to do with the theme because I´ve already
   used this plugin with the actual theme several weeks ago and it worked properly.
   Do you think it has to do with PHP version / activating or deactivating any PHP
   extension?

 * I noticed that the problem persisted with all plugins being inactive, but if 
   your theme contains any reference to `woosync-premium/external/callbacks.php`,
   and this file is still there, this would explain the error.
 * You can confirm this by removing or renaming the woosync-premium directory. The
   error should then change to not finding the file.
 * Look through your theme’s functions.php file (and other PHP files) for possible
   references to woosync functions and inclusions.

 * Hi Gal!
 * Since I´ve deleted Woosync from my website, I don´t get no more fatal errors 
   referencing this plugin so that shouldn´t be the problem.
    Still, I can´t solve
   the issue with Product Feed pro (now my fatal error logs are something like this:“
   Maximum execution time of 30 seconds exceeded”)

 * In your PHP settings, change `max_execution_time` to 300 or more (I use 600).

 * Hi!
 * We´ve asked the host to push the execution time to the maximum and still, cannot
   make this plugin work.
    Now we are getting a 500 error. Do you think it is possible
   to solve this issue or should I move to another plugin?

 * 500 implies there’s something in your error_log or wp-admin/error_log you can
   look at. Copy and paste it here.
