I need some serious help here!
I've used this contrib for a long time with NO problems.
Suddenly, it just stopped working!
No transactions go through... I look on Authorize.net page and there are no transactions as unsettled being attempted.
What could have possibly changed as my host assures me nothing has changed on the server?
After emails with my webhost, he tells me:
"You still have an old version of PHP (4.3.11), so it has not been recompiled in a while. MySQL seems to be at 5.0 however. Was it always at that?"
Not quite sure what he's asking/telling me here.
The only thing I've done different to the store is the SSL expired today, and I renewed it and installed... and it's up and working just fine!
It's almost like its stopped "talking" to authorize.net, but nothings different.
I've tried using a new key, etc. It won't even work at all in test mode.
Any help or guidance would be MUCH appreciated.
