Getting the following error at the top of the plugin settings page:
"Legacy Page Cache rewrite rules have been found. To remove them manually, edit the configuration file (/home/website/.htaccess) and remove all lines between and including # BEGIN W3TC Page Cache and # END W3TC Page Cache markers inclusive. Or if permission allow this can be done automatically, by clicking here."
Clicking the auto-remove does nothing. Is this error something I should be concerned about? Should I remove the information manually as it suggests?
