Wordpress LScache Plugin: Failed to create Optimiser table
Last Updated on: Wed, 15 Apr 2026 00:00:02 Ive installed Litespeed on a few sites in the last couple of days and on every one Ive seen this error notice on the Optimise tab. Failed to create Optimiser table. Please follow Table Creation guidance from LiteSpeed Wiki to finish setup. I originally installed the plugin on WP Engine (for the optimisation and media options, not the cache) so put it down to an issue with permissions. But now installed it on another server running Litespeed and getting this message. I think something is up with the plugin. Hi @bonkerz, could you please check is xxx_litespeed_optimizer (xxx = your wp prefix) exists on your database? If not, could you try to run this query manually: https://gist.github.com/stanleybz/4270ededbcb11ae20873b246f3082cbe Please let us know if you find any query error. If its created successfully please also remove the table youve created.
