I followed @pzxyz’s suggestion on testing the custom code for functions.php. Turns out, it was these 2 code snippets that were meant to optimize my results on web tools that were the culprit:

/***** Start: Defer parsing of javascript *****/
function defer_parsing_of_js ( $url ) {
  if ( FALSE === strpos( $url, '.js' ) ) return $url;
  if ( strpos( $url, 'jquery.js' ) ) return $url;
  return "$url' defer='defer";
}
add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );
/***** End: Defer parsing of javascript *****/

/***** Start: Remove query string from static resources *****/
function _remove_script_version( $src ){
  $parts = explode( '?', $src );
  return $parts[0];
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
/***** End: Remove query string from static resources *****/

I commented them out and got no errors anymore. Even got the blank page on editor issue resolved as well.

*Additional note: I was using the autoptimizer plugin and I had to disable minification on javascript and css files. This solved issues on console errors on post pages.

Yes, I do, lots of it actually. I’ll try minimizing it to see if that’s the cause of the issues.

Thank you. I already posted in that forum, I thought I could get more help by posting on this site as well to see if any other users had similar issues.

Found the issue. It was caused by child theme incompatibility for my website. I was using a custom Divi child theme and somehow all these issues popped up.

Tested reinstalling wordpress and deactivated plugins but still having a blank page on page edits.

Having these errors on wordpress admin dashboard as well, might be related:

I’ve had this one too and I thought it was the jetpack module at first, so I tried disabling it as well as Autoptimizer plugin, but issue is still there. I think minifying them with Autoptimizer might have been the cause but I’m not too sure. Someone needs to verify.

@heator Thank you very much, it works now. Lol, i don’t know how I missed this on the docs, I guess I was in such a rush I probably referenced the wrong one a couple times. Good stuff! ??
