Hi,

How can we guess, since you provide no data.

Post the full critical error (if there are no details, enable Wordpress Standard Debug to a log).

Also is that a an upgrade? What version? Any addons for wpForo?

Hi @fahadurk,

Please check and do the following steps:

1. Please deactivate current addons or update them to 3.0.0 version before updating wpForo to 2.0.x
2. Deactivate Go2wpForo tool if you have installed and done forum migration
3. Make sure you don’t have old forum template files in /wpforo/ folder of your current active WordPress theme directory /wp-content/themes/your-active-theme/. If you see that folder, please rename it.
4. After the update to 2.0 version, go to wpForo > Tools > Debug admin page, make sure there are no errors in Errors & Issues Tab
5. Then go to Database Tables tab in the same admin page and check the database issues.
6. After the update, please delete all caches and purge CDN if you have.

How do I install WP foro 2.0?

Because as soon as I am clicking active, it is showing me the error message.
