# [NSFW] Critical error

 * I use this plugin now a few months, and install it to multiple site. This is 
   the 6th website I have installed on. But first time I got error.
 * The error appeared after I had added Tenient/Secret/Client ID it then broke and
   says critical error look at e-mail.
    When I look in e-mail, I see the following:`
   Een fout van het type E_ERROR werd veroorzaakt op regelnummer 42 van het bestand/
   home/abdullah/jcparfum.nl/public/wp-content/plugins/mail-integration-365/libs/

   wp-content/plugins/mail-integration-365/classes/`
 * Meanwhile I pressed “save credentials into database”within the plugin, now I 
   get standard this.
    Thanks in advance, and curious why this happened, I cannot
   use this plugin anymore, on this site..
 * Update: I saw another thread about grizzly which had been fixed. So maybe it 
   is handy if I share all my plugins:

 * I have found the plugin which causes this plugin to fail, it is called:
    Google
   Listings and Ads from WooCommerce ([https://wordpress.org/plugins/google-listings-and-ads/](https://wordpress.org/plugins/google-listings-and-ads/))
 * I disabled it, and now everything works again.
 * But I need WooCommerce Google listing, such that webshop products show up in 
   Google.
    Could you please let me know if you would like to fix this, and when
   you expect to fix it? Thank you in advance, and much lovee for this 🙂 <3

 * Hi [@adamtechbv](https://wordpress.org/support/users/adamtechbv/), having downloaded
   this Google listing plugin, it looks to have several errors. Indeed, when activating
   it I get the following message: _“The plugin generated 576 characters of unexpected
   output during activation. If you notice “headers already sent” messages, problems
   with syndication feeds or other issues, try deactivating or removing this plugin.”_.
 * I’m afraid I can’t fix other plugins issues, but suggest you get in touch with
   that plugin’s support page to see if they can resolve the issues with their code.
