I have the same problem. Optimize tables is greyed out. I have a mix of InnoDB and MyISAM tables.
Tables using the InnoDB engine (51) will not be optimized. Other tables will be optimized (11).
The other tables are MyISAM tables.
If I select the “Optimize InnoDB tables anyway” option, the optimize tables is no longer greyed out.
How can I only optimize the MyISAM tables?
I have the same error and 2 others:
Warning: join() [function.join]: Invalid arguments passed in /public_html/wp-content/plugins/yet-another-related-posts-plugin/magic.php on line 27
Warning: Invalid argument supplied for foreach() in /public_html/wp-content/plugins/yet-another-related-posts-plugin/magic.php on line 54
I am using Atahualpa.
