The server was built on PHP 8.2 and was working fine, but downgrading to PHP 8.0 caused 502 Bad Gateway white page errors.

Reverting back to 8.2 and even upgrading to 8.3 resolved the issue.

The reason why I want to revert to 8.0 is because Elementor is stuck on the loading screen. It doesn't look like I'm the only person experiencing this issue because a Reddit poster claimed that downgrading to 8.0 resolved this issue for them. So I wanted to try it.

I've already tried resaving permalinks, disabling PHPFINFO through custom config, drastically increasing the WP memory limit, and my vhost has try_files $uri $uri/ /index.php?q=$uri&$args; in the location context.

Top doesn't show high CPU usage and no relevant errors in the PHP error log.

I've tried changing Elementor themes and disabling all plugins except for Elementor, but no dice. I haven't tried rolling far back to a previous Elementor version because the latest update is a security release.

 

When I built the server, this was also in my custom config btw:

Code (Text):

PHP_PGO_ALWAYS='y'
PHP_PGO='y'
PHP_BROTLI='y'
PHP_LZFOUR='y'
PHP_LZF='y'
PHP_ZSTD='y'
ZSTD_LOGROTATE_NGINX='y'
ZSTD_LOGROTATE_PHPFPM='y'
NGINX_ZERODT='y'
NGINX_LIBBROTLI='y'
NGXDYNAMIC_BROTLI='y'
AUDITD_ENABLE='y'
PHP_OVERWRITECONF='n'

But I removed it and rebuilt nginx/php-fpm to test.

 

Just added those and recompiled php-fpm but didn't work

I'm upgrading back to 8.3 now

 

I don't really have a need to anymore. I found the bug in Elementor Pro that's affecting people right now so I just disabled the feature (FontAwesome Pro)

But I think the logs would have recorded it already so I can maybe search for it?
