I updated my site to WordPress 6.9, which caused a critical error. I manually downgraded WordPress to the previous version, but the critical error is still occurring. I can no longer access the WordPress admin dashboard. I also received an automated email from WordPress indicating that the issue may be related to the tagDiv Composer plugin.
Current plugin: tagDiv Composer (version 5.4.2 | built on 22.10.2025 10:59)
Hi,
In situations like this, you need an FTP or cPanel acess, set the debug to true to see exactly what is causing the problem. After that, if it is a plugin like tagDiv Composer, rename the plugin (this can be done using FTP or cPanel, renaming the plugin will disable it from the site).
