I have a single theme. When I remove the newsletter signup block, save and flush the cache, nothing happens. When I add another featured block, nothing happens. When I make any changes to the single template, nothing happens.
That's the problem.
Is there a group of files, that can be manually uploaded to replace the single theme as it seems to be corrupted. If so, how is it installed, as I can download the 1.2.10 and upload as needed?
Thank you for ideas.
