All subdirectory sites defaulted to main domain

Hi,

Decided to try out your premium version after over a year of having purchased it. Everything seemed to go fine last night, but this morning I couldn’t get to any of my sub-directory sites. They all kept defaulting back to the original main domain URL. Does any of this sound familiar?

Only realized it was due to your plugin after deactivating it in my main site. So I’m now back on my original caching plugin.

It’s not a multi-site mind you, just separate sub-directory installs.

Can you give me any pointers on how to avoid this problem in the future should I give your plugin another run through?

thanks in advance.
