Trying to delete a batch of events triggers error: 0 Joomla\Filesystem\File::delete: Failed deleting inaccessible file index.html

Hi,

I am trying to clear out old events but keep getting issues (including freezing of screen) when I try to delete on mass. In events I set the show to 100 events (as all is worse - frozen screen mentioned above) and select all and the click delete but it causes error:

0 Joomla\Filesystem\File::delete: Failed deleting inaccessible file index.html

I did try searching for the events table in mysql to delete them that way but the table isn't there or at least it isn't under the events part of the social tables so not sure.
