Errors when upgrading

[balburl]

Hi, 

I am trying to upgrade from version 1.6.0.13 to the current version using the one-click upgrade. I get an internal server error each time I even try to delete and re-install one-click upgrade. I've contacted my host and they have increased the php to the max allowed and still get the same error message. They say it has something to do with "classes."  I do have this same problem with another module that used to work and now doesn't when I try to configure it. 

 

Am I doing something wrong? I have my shop in maintenance mode now. I sell downloadable products only and each product can have multiple combinations from which to choose.

 

I will attach a snip from the chat below.

 

In my configuration information I notice that two files are missing:

• psadmin/autoupgrade/index.php
• psadmin/autoupgrade/backup/index.php

Could this be the problem? If so, how do I get those files back?

 

Any assistance would be appreciated. I am hoping that upgrading will be the answer to the problem . . . if only I can do that!

 

Thanks,

Brenda

I think the problem isn't related to the index.php files nor the error mentioned in the chat.

Any idea as to what the problem might be?

 

Thanks!

It can be anything. The reason is not yet clear. Anyway, I can fix it (PM).
