Hi Michael,
Only 100 files or something like this. We have done a lot of testing and noticed that blank page occurs when there is a lot of folders, not a lot of files.
We can see the /images folder Ok with more than 500 files and only 8 – 10 directories.
I can prepare link with subfolder list to allow you see the problem and also another link with no subfolder list to allow you see the number of files.
We only need a component (or module) that shows files and subdirectories. Some years ago we developed our own code http://www.alvaco.es/index.php/Descargas but is php and not integrated with Joomla and we would like to have integration (folder rights … etc). No need to have fields or personalized fields.
The new site we are building / testing with Joomla 2.5 is new.alvaco.es
Also we purchased puretabs and found problems but will inform you in a different post.
