Today I've upgraded a site from v2.5 to v2.7, and now it seems to not keep alive the connection with the database, allocated in another server.
This message appears sometimes :
Error 2 (net::ERR_FAILED): Unknown error.
The DNS are OK, all is ok but the fact is that it doesn't keep the connection as it used to do in previous versions (2.5)
Please, I can't stand this situation long time without reverting to older version, so please can anybody help me?
Thanks in advance
