@plaurits,

Please provide the following information.

1. Do you have any wpForo addon installed? Can you deactivate them and check it again?

2. This looks like Elementor plugin conflict. Can you please deactivate the Elementor for a few minutes and check the forum again?

3. Make sure wpForo is installed correctly. Deactivate wpForo, delete it (just delete, do not click the uninstall button), then search and install wpForo plugin again. This will not delete any data or configuration

4. Deactivate other plugins and activate them one by one and check the problem.

5. make sure you don't have old customized wpForo template files in the current active WordPress theme in the file system: /wp-content/themes/your-active-theme/ directory. If you have done some customizations, the template files are located in /wpforo/ folder of that directory. You should delete that folder and rename or remove all customizations.

6. Make sure you don't have code snippets related to wpForo in the functions.php file of your current active WordPress them or in Code Snippets plugin.

Hi

RankMath has acknowledged the issue on their side, see extract from RankMath case:

Hello,

We will implement a permanent fix in our plugin in an upcoming update. The changes made in the WPForo files are a temporary solution to resolve the issue on your site.

Please don’t hesitate to get in touch in case you need our assistance with anything else.

Thanks.

Hello,

We were able to reproduce the error and have logged it. Please allow us some time to test and release a fix.

It should be added to the plugin in the upcoming update. You can keep an eye on the changelog and we will be mentioning this error when fixed.

For now to fix the issue on your site please add the following code on line 289 before $this->init_base_classes(); in plugins/wpforo/wpforo.php file:

if ( ! empty( $_SERVER['REQUEST_URI'] ) && strpos( $_SERVER['REQUEST_URI'], 'sitemap' ) !== false ) {
    return;
}

I hope that helps. If you need any other assistance, please feel free to let us know. We are here to help.

Thank you.
