Hi tinibop
I also have the same problem. My admin was locked after w3 totalcache install and activate. I followed advice on deleting the w3 files manually and deactivating the plugins via the database. I also tried to default to the default theme by renaming my theme but no luck. The browser eventually returns a timeout error. It was up and running before this happened. I think some file has become corrupted —anyone out there who can help us
