Now we have this error :
Failed to reset cache for the instance #13: WordPress Toolkit was not able to finish running an operation on this site in 180 seconds, so the operation was terminated. This could mean that your WordPress installation might be infected with malware. Check the wp-config.php file of the installation for potential malware code or run an anti-virus scan. If you cannot find any traces of malware, try running the operation again later.
But in fact that run more than 15 minutes before to throw the error. This not normal a ~350Mb ishh web site who took normally about 3 minutes to copy become out of memory/time out with 1 more line in the wp-config. The content remain the same in both case. You clearly have a bug or a not implemented support in your tool. The tool clearly doesn't recognise the line and he don't know what to do with it, so considered it as malware stuff.
Thank you!
