[SOLVED] Problem with extension/module in 1.5.5.1

On my main site i get an error message when i go to admin - extensions - modules:
Opera: You tried to access the address http://xxxxx/admin/index.php?route=exte ... &token=xxx, which is currently unavailable.
Internet explorer throws an 500 internal error.

On my test server it works fine.

I dont have any special modules installed, its "out of the box" version.

I have checked that the extension / module folder exist, checked module.php and a lot more files I suspect are connected to this. I have also deleted and uploaded again many files to see if they were corrupt. Language files and template files are checked

I would hate to do a full reinstall, as a lot of config is done.

Anyone got any suggestions for me as to what to investigate further ? TNX!

perhaps there are problems with the server..

Hmm, I find that unlikely. Both are on same hosting provider. I dont see why only that exact file (or whatever the problem is) should be unreachable, when everything else seems normal.

I am going blind here, been looking at files for hours now :/

Sorry to not provide a full solution to your problem, but in my experience response code 500 usually means that the php code is invalid (wrong syntax etc).

I have spent much more time than I'd like to think about, trying to solve similar problems just to find that I've missed a semicolon on a row. Or my favorite when I had by mistake written "=" on a row that should have read "=>". Took me hours to find that one.

I found the error

Corrupt files... Have never had that problem before. Maybe filezilla is bugging me ? Who knows...

I just had a very good learning curve, new to opencart

I found some errors in the error log (from corrupt files), but not thisone.

I had to set php.ini to register error,then I found a problem i google_talk. That file was bloated to 4 kb, although content looked good in notepad. Overwritten by new correct file of 950 b something. Solved (for now, I bet there are still som surprises out there )

Thanks for setting me in right mindset, to enable php errors, that lead me straight to the error
