[Forum] 4.1.11 Upgrade error

[Haazen]

I uploaded 4.1.11 over 4.1.8

Running ../install/upgrade.php gives the following error:

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Unknown MySQL server host 'my.host.com ' (1)
/ my host bla bla /htdocs/includes/class_core.php on line 317

I contacted the hosts tech support. His response follows:

i have found that a line of code in that file is causing the database script to not connect. catch_db_error will handle exiting, no infinite loop here. I am recommending changing the infinite loop call to allow the script to work properly.

I did a double check to make sure ALL new 4.1.11 files were uploaded and double checked the database name and password.

Recommendations please??

Well, using the correct mysql information, will resolve the issue. The issue is that mysql cannot make a connection to your my.host.com server. Are you sure its not localhost?

Thanks for your response. Let me ask. After posting here, I found that not all 4.1.11 files uploaded correctly. class_core.php was one that was still 4.1.8 when I first tried to upgrade. After I found this and made sure all files were uploaded correctly, I tried upgrade again and got same error.

My worry is first time corrupted the DB. I have since restored the DB to 2 days ago but am apprehensive to try upgrade again. Could 4.1.8 class_core.php corrupt my database trying to upgrade to 4.1.11. Hope this question makes sense.

No, it couldn't. The error you got above has NOTHING to do with a corrupted database. It is just the wrong mysql information, nothing more, nothing else.

Thank you. My bad. There was a space after .com in the server name. Sorry for the waste of time. Now thinking back in my feeble mind, this happened last time I upgraded. I believe I am 'sleep editing' config files. Again, sorry for the waste of bits and bytes.

Not a waste of time, just learn from it and remember for the future.
