Cornerstone load issue with WP multisite installation

[referee]

Hi,

Just updated WP to the latest 6.9 version and some plugins, including WPML. Now Cornerstone doesn’t load as it should on subsites of the network.

If I disable WPML and all its add-ons, it loads as expected. The fix is to ensure that the new Setup Wizard of WPML is completed after its recent update.

Hi John,

Thanks for reaching out.

The screenshot you shared indicates an issue accessing the Themeco API endpoints. This is likely caused by mod_security being enabled on your server, which can block the Cornerstone endpoints required to load pages or posts.

I recommend contacting your hosting provider to temporarily disable ModSecurity or whitelist the necessary Cornerstone endpoints. The following articles may be helpful:

Additionally, if any WPML addons are in use, please verify whether they might be triggering or enforcing mod_security rules.

Thanks!
