Here is what I can see based on the log. * The error occurs because the MySQL query SHOW CREATE TABLE is failing and returning false instead of a valid result. This happens when trying to export the database. * Most likely causes: 1. One or more tables might be corrupted or have issues 2. The database user lacks permissions to run SHOW CREATE TABLE 3. Special characters in table names but this is unlikely 4. The connection drops during the export process also unlikely * To diagnose: – Run CHECK TABLE on all tables to identify corruption – Verify the database user has full privileges – Look for tables with special characters or unusual names * Since it works on other sites with the same setup, it’s likely a database-specific issue on that particular site. * Plugin Author [Yani](https://wordpress.org/support/users/yaniiliev/) * (@yaniiliev) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/php-8-85/#post-18570076) * Could you also try this modified version of the plugin: [https://www.dropbox.com/scl/fi/xo9ni2chbxgbqo6u6z1tr/all-in-one-wp-migration.zip?rlkey=sq4jc5hibct2p560xgcmo4clr&dl=1](https://www.dropbox.com/scl/fi/xo9ni2chbxgbqo6u6z1tr/all-in-one-wp-migration.zip?rlkey=sq4jc5hibct2p560xgcmo4clr&dl=1) * See if it is any different on PHP 8. * Thread Starter [MaxByer](https://wordpress.org/support/users/maxbyer/) * (@maxbyer) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/php-8-85/#post-18570085) * Ok I will try the mod version and get back to you! * Thread Starter [MaxByer](https://wordpress.org/support/users/maxbyer/) * (@maxbyer) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/php-8-85/#post-18570090) * Is it possible low disk space could be an issue? * Plugin Author [Yani](https://wordpress.org/support/users/yaniiliev/) * (@yaniiliev) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/php-8-85/#post-18570091) * If the MySQL server is on the same server and the server runs out of disk space, it is possible for MySQL server to stop responding to some queries but you will see a lot more errors than just this one. * Thread Starter [MaxByer](https://wordpress.org/support/users/maxbyer/) * (@maxbyer) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/php-8-85/#post-18570116) * Your mod plugin WORKED!!!!!!
