 * Bare in mind that the files you need to exclude via the ignore list, are not 
   always obvious. It could be a completely unrelated file causing it.
 * The error is telling you that you merged a js file that expects ‘memoize’ to 
   be defined earlier, possibly, it’s an inlined script.
 * First check i you have anything else, another plugin for example, altering the
   order of scripts, or removing unnecessary scripts, or how the scripts work.
 * Then you can start by adding all files in the header to the ignore list, and 
   remove one by one until the error shows up.

 * Hi, thanks for the quick response. I’m going to have to play something here. 
   The error only occurs with a plugin that I have installed on all pages.
 * I have already migrated all files from this plugin. I deactivate the plugin everything
   runs without error message.
 * Thanks for Support

 * Which plugin was it, just out of curiosity?
    Something custom made, or is it 
   a free/paid plugin?

 * GDPR All in one for WP, it works great and do what it should. The error messages
   have already been passed on.
 * Maybe you can add an exception here directly in the plugin?
 * Thanks again for the support
