MyBB Community Forums

As far as I may see, mybb even 1.8.29 is incompatible with PhP 8

I tried to upgrade to it and the top of my forums showed all sorts of error codes, and then the sites won't even load and it seems to crash my entire server too.  The errors refer to google_seo and the template I am using.

The following warnings occurred:
Warning [2] Undefined array key "extra" - Line: 100 - File: inc/plugins/google_seo/url.php PHP 8.0.13 (Linux)

I disabled the Google_seo plugin, and still got these errors:

and even with Google_SEO deactivated still the site will not load at all under PhP 8.0

Hi Mdawg

My provider is Infomaniak.ch.

I've installed mybb_1829.zip (from https://resources.mybb.com/downloads/mybb_1829.zip) 2 days ago, with french translation and roundo theme. Any plugin.

My server run in PHP 7.4 but my provider offers the possibilitiy to change the PHP version in one click.

I've tried  PHP 8.0 few minutes ago and i don't have any problem. Forum and admin runs well.

My DB is MariaDB : 10.4.

Correct, MyBB does not currently support PHP 8.0

https://docs.mybb.com/1.8/install/requirements/

https://github.com/mybb/mybb/issues/4138

Hi, any update on PHP 8 support? Currently running MyBB v1.8.31 - thanks

MyBB supports 8.0, I believe there are still some fixes for 8.1, but plugins and themes will be hit and miss.

Thanks. 

I tried to upgrade to php 8 but got a few errors from what looks like core files. I might be wrong though:

Warning [2] Undefined variable $avatarep_script - Line: 10 - File: global.php(958) : eval()'d code PHP 8.0.25 (Linux)
File Line Function
/inc/class_error.php 153 errorHandler->error

/global.php 958 eval

Warning [2] Undefined variable $unreadreports - Line: 54 - File: global.php(961) : eval()'d code PHP 8.0.25 (Linux)
File Line Function
/inc/class_error.php 153 errorHandler->error
/global.php(961) : eval()'d code 54 errorHandler->error_callback

I have a clean installation of 1.8.31 with php 8.1.12

All wors good

But i have not tested any update yet.

$avatarep_script is from a plugin, $unreadreports is from an outdated theme as the variable was removed but is still in the template.

new registrations using PHP email authentication fails with any PHP version greater than 7.4
Tested today on version 1832 of MyBB

What is the error you're seeing? I don't believe we've had any other issues with this, and the PHP mail() function is just a core PHP feature, there shouldn't be anything different there.
