Uloding Upgrade 7.4.4 to 7.6.6 Issue

I have download the 7.4.4 to 7…6.6 upgrade now 3 times. Each time I try to upload the uprade bundle, the system exits back out to the Main dashboard. No errors, no status, no nothing.
Does anyone know what is causing this and how to correct it?

are you sure that there are no errors? can you check you apache log? have you changed your max file size upload?

best regards

Thanks for responding. No, I had already set the upload size, memory size, and other items prior to the upgrade attempts.

I re-checked the upgrade document and found a setting not matching for response time. Our setting was large enough, but I increased it to a larger value and that did the trick.

This is resolved.
