 * Hey, there!
 * Are you running PHP 8.1 or newer? I’ve had a few reports of an issue, and each
   time it’s turned out to be another plugin that isn’t compatible.
 * If not, please shoot me an email at sociallinkpages.com/contact so I can get 
   credentials from you to sign in and take a look.
 * Thanks!

 * Thank you for digging in! That’s the kind of issue I’ve come across a couple 
   of times before. You’ll need to contact w3-total-cache and let them know about
   that. :-\

 * hello [@gelform](https://wordpress.org/support/users/gelform/)
 * that’s interesting, everybody else can do debugging, why can’t you?
 * if you are not able to tell me what you want to know, we can do TeamViewer please
   tell me how to connect to you. nevertheless, I prefer you tell me what you need
   like anybody else doing troubleshooting on this platform

 * I can’t speak to other developers being able to debug without having access to
   the site they’re trying to debug.
 * Let’s start over. Where do you see the 500 error? If you deactivate the Social
   Link Pages plugin, the error goes away?
 * Are the logs still showing the error coming from plugins/w3-total-cache
   Unsupported
   operand types: string * int in wp-includes/functions.php:75? If so, what makes
   you think it’s the Social Link Pages plugin?
 * Thanks!

 * yes, let’s start over:
 * the page vaegabond.com/links is created by social link pages plugin, so obviously
   if I deactivate the plugin, the error goes away as the page itself won’t exist
 * Logs are still showing same thing, as long as I don´t comment out the specific
   line, describe in this topic
 * If I comment out this line, the logs showing:
 * PHP Warning:  Undefined variable $date in /var/www/virtual/haengmat/vaegabond.
   com/wp-content/plugins/w3-total-cache/Generic_Plugin.php on line 490
 * all the answers to your questions have been answered before. please make yourself

 * Thank you! I’ve once again reviewed this thread and the thread you started with
   W3 Total Cache.
 * I understand the issue is that the page [https://h/vaegabond.com/links](https://h/vaegabond.com/links)
   is no longer loading. However, the php logs indicate the issue is with W3 Total
   Cache. You say, “seems like its related to your plugin after all” but I don’t
   see anything in that thread indicating the issue is with Social Link Pages. If
   commenting out a line in the W3 Total Cache plugin fixes the issue, and their
   support agent said you could keep it commented out, it sounds to me like that
   is the best solution.
 * You can hide the php warning from your wp-config.php file.

 * hi
 * I am not saying its related to your plugin, W3Total chache is saying this. Please
   read carefully. I am just in the middle trying to get you guys working together
   instead of pointing fingers.
 * commenting out a line is not the best solution, its the quickest solution that
   wont add work to your desk and you can mark this as complete.

 * Agreed! But I must be missing something. I just re-read the support thread with
   them. Where does W3 Total Cache say the issue is with Social Link Pages?
 * Thanks!

 * for now I commented out the line, so just in case you want to troubleshoot, let
   me know and I will set back to normal

 * Again, their hunch doesn’t give me any information. Seems like we’ve reached 
   an impasse. I would recommend commenting out the line, hiding the php warnings(
   since it’s a warning, not an error), and calling it good.
