Re: Wpforo Page spiking CPU usage to 100% and then 503 error, Not getting opened

@urrahul1, There are no specific known issues documented in wpForo related to high CPU usage or 503 errors triggered by board or forum creation, particularly with PHP 8.2 and LiteSpeed server. However, some users have reported performance issues such as slow posting or slow import processes, but these are not directly linked to PHP 8.2 or LiteSpeed. If you experience such problems, it could be related to server configuration, plugin conflicts, or other external factors rather than wpForo itself. For example, one case mentioned a background process causing database overload, but it was concluded that this was not caused by wpForo but possibly by another plugin or malware. It is recommended to check server logs, disable conflicting plugins, and ensure your environment is compatible with wpForo requirements. If the issue persists, providing detailed logs and environment info to wpForo support would be helpful.

Wpforo Page spiking CPU usage to 100% and then 503 error, Not getting opened

Hi Team,

I have been facing a persistent 503 Service Unavailable error on my wpForo forum page (/community) for the past three days.

I have already performed extensive troubleshooting, including:

Deleting and reinstalling wpForo twice
Completely removing previous forum data (data size was minimal)
Disabling and reconfiguring caching
Switching PHP from 8.3 to 8.2
Verifying server resources and limits

Each time I reinstall wpForo, the forum initially loads correctly. However, as soon as I start creating boards and forums, there is a sudden spike in server usage, after which the forum page stops loading and consistently returns a 503 error.

This makes me suspect that there may be a specific database query, background process, or loop triggered during board/forum creation that is causing excessive CPU usage or getting stuck.

For reference:

WordPress version: 6.9
PHP version: 8.2 (previously 8.3)
Hosting environment: LiteSpeed server
Forum was working perfectly for over one month before this issue started

Could you please advise if there are any known issues related to board creation, queries, or compatibility that could cause such behavior?
