This file has not changed since September 27th, 2012. I am not sure what's wrong with your site, but JPane really is available in Joomla! 2.5 and this code does work for everyone else for over a year now.

I have more information now.

The error only appears to items marked 'Modified'. I hope that helps. Again, I did not have this issue with 2.5.5.

Thanks.

I cannot reproduce this issue. Moreover, as I stated, this code hasn't changed for over a year. The last change was back in September 2012 when I added a conditional to cater for the then just released Joomla! 3.0. I will investigate further, but if I can't reproduce this issue I am not sure if I am going to be able to fix it :(

Thanks, Nicholas. I will also try to figure out if it's tied to a function or a different component. Will update the thread if I find anything else.

I had a sudden inspiration. It's because you are calculating diffs for modified files and, yes, this is a bug that's there for a year. It's just that nobody had reported it yet. Go to the component Options, click on the "File Scanner" tab and set "Calculate diffs when scanning" to No. Click on Save & Close. Make a new scan and now try seeing a modified file. The page should load. Is this correct?

That did the trick. But it is a bug, correct?

And thanks for the answer! But what actual difference will this make for the file scanner turning diff calculation off?

It is a bug that's there for over a year, as it seems. Turning off the diff calculation causes the code never to be called. There is no change to the way the scanner works, there is only a difference in the way it presents and stores the results. When calculating a diff it will save the contents of each file inside the database. It will then use this stored data to compare with the current version. This consumes huge amounts of database space. Otherwise it will only check the MD5 checksum and the modification date of the files. Practically, not using the diffs results in faster (and equally secure) scanning without the huge database overhead. That's why this option is disabled by default.
