XF 2.1 Problems with PHP 7.3

[interforo]

After upgrading my server to PHP 7.3 I have issues when users posts

They get this error and apparently is only on private messages

ErrorException: [E_USER_WARNING] [WebPush] gmp extension is not loaded but is required for sending push notifications with payload or for VAPID authentication. You can fix this in your php.ini. in src/vendor/minishlink/web-push/src/WebPush.php at line 72

From the error, "gmp extension is not loaded" have the host enable it.

 

[interforo]

Server said it is installed

 

[Ozzy47]

Maybe not for that PHP version. What does it show it out ACP server environment report?

Yeah, I had to reinstall GMP when I upgraded my PHP too. This is how it's done on my host. Your host/server may vary.

We had no problems with 7.3 and now 7.4 Could it be an add-on installed that needs an update from the author?

Zero issues with 7.3 or 7.4 for me. I use a VPS so update everything myself, though.

It's not a problem with Xenforo or PHP or them working together, it's that when you move to a new php version you will likely have to (re)add the GMP extension to it if your web host doesn't add it by default. It may be different for other people but for me the way my server works is I got folders for different versions of php and each has its own subfolders of extensions. So if I move from 7.2 to 7.4 the 7.4 process is going to look in its own folders to see what extensions are there and even if I installed GMP earlier when I was using php 7.2, it won't find it until I install and enable it for php 7.4. On some systems you would edit php.ini or php.rc to add the extension and I'm sure there's other ways to do it based on your setup. I hope that explains things better.
