The problem I am having is not actually with uploading files but with the batch-add interface getting stuck at the folder selection. The symptom is the same in both browsable and non browsable presentation.
After selecting a folder and clicking the OK button the browser requests searchnew.php?startdir=misc but searchnew.php seems to be unable to process the parameter and displays as if it were not present.
I have seen this error show up before on the forums with a variety of causes, for me it effects all folders in /albums and started with a previously working installation of 1.5.26. After the error first started I upgraded to 1.5.28 and still have the same problem.
I have followed suggestions in similar posts, re-written file permissions (all files and folders 777) and checked for the use of special characters.
All of my /albums sub folders are named with only lower case alpha numeric and underscore characters.
examples of sub folder names are: clients, projects, products, mtc, lcd, story_chairs, misc.
I have read http://documentation.coppermine-gallery.net/en/upload_troubleshooting.htm
and followed as many of the procedures as I can. I have not posted test user credentials as batch-add requires admin rights.
Single file add and multiple file add both work with no debug warnings.
Batch add shows the following debug warning:
Warning line 449: preg_match() [function.preg-match]: Compilation failed: invalid range in character class at offset 18
The gallery is located at www.showtrek.com/project_gallery/
I have copied the gallery, albums and database to my windows desktop (with XAMPP Apache and MYSQL environment) but I cannot replicate the error on my local machine.
I have also re-installed the gallery on the web host (keeping the database and albums folder and deleting everything else).
Can anyone suggest a possible cause for the error in this case?
