I have been trying to use templates. 3 times it failed for WP and 1 for openclaw. All give the same 502 bad gateway response. I feel like something is wrong. Am I missing something?

Did you recently change any environment variables, and is the service listening on the correct port?

For openclaw, I only set the password, the template set the others. I reviewed them, wasn't anything related to permissions, more about info storage locations. The url would never resolve, I was never able to figure out how to get started. I deleted that install.

I just got a WP install started with the agents help - I don't think it used a template. It just chose the wordpress insatll + maria db combo for it after a few questions. At first it was giving back a 403 error. Then it resolved. I was trying to setup a basic WP install and got stuck connecting the database, I looked in the env's and pulled the connection info, user and pw in.. but not luck connecting.

Still trying to figure out how to install WP sites. I will try a few more templates and see if I can recreate the issue.

Was able to fix using the agent. Took a bit of encouragement, but after this message I asked it to apply this change and it is showing the install page now.

Oddly - I was not able to even after the fact, figure out how I could do this manually.

Is it even possible to adjust the system in the suggested manner here without the agents help?

Found it. Your WordPress service is crashing due to an Apache configuration error:

Error:AH00534: apache2: Configuration error: More than one MPM loaded.

Root cause: Your start command is appending configuration to /etc/apache2/apache2.conf, but Apache already has multiple MPM (Multi-Processing Module) modules enabled, which is a conflict.

Fix: Update your start command to disable conflicting MPM modules before starting Apache. Replace your current start command with:

/bin/bash -c "a2dismod mpm_prefork mpm_worker mpm_event; a2enmod mpm_prefork; echo 'ServerName 0.0.0.0' >> /etc/apache2/apache2.conf && echo 'DirectoryIndex index.php index.html' >> /etc/apache2/apache2.conf && echo 'upload_max_filesize = 50M' >> /usr/local/etc/php/php.ini && echo 'post_max_size = 50M' >> /usr/local/etc/php/php.ini && docker-entrypoint.sh apache2-foreground"

This disables the conflicting modules and enables only mpm_prefork before starting Apache. Once you update this, redeploy and it should stay up.
