Error: Server contacted but Gallery not found at this URL

Hi people,
after a couple of days of searching I'm no closer to resolving this issue with Gallery 2 for myself so I'm compelled to ask for your kind assistance.

I'm not particulary interested in using GR to upload images, I'm mainly concerned with the fact that when I try to use the 'Fullscreen Slideshow' function, either from within my Wordpress embedded verion or standalone I get the dreaded "Error: Server contacted but Gallery not found at this URL (http://www.southerns.net/shadowshow/main.php)" problem.

I've tried creating the fake 'gallery_remote2.php' file to return a 404, but this doesn't seem to help - although when I navigate to http://www.southerns.net/shadowshow/gallery_remote2.php I get a blank page which puzzles me.

I've tried deleting and re-installing the relevant modules.

I've also updated my Gallery to 2.2 rc1.

The other thing which puzzles me is that I have an almost identical installation here - http://www.ruralramblings.co.uk/blog/wp-gallery2.php where the Fullscreen Slideshow works fine.

Thank you for your patience, I hope to hear from you soon because it's driving me ever so slightly potty

Hi paour,
thanks for your speedy reply and for your attention.

I realised there may be something amiss with the fake gallery_remote2.php file, but I created it as per the instructions in the FAQs. i.e. included the brief snippet of php in a new file named as above. I then uploaded it via Dreamweaver and there it sits in the gallery2 folder (named 'shadowshow' on the server).

I seem to have followed the instructions to the letter, but is it possible that I've somehow missed something out? (I'm perfectly prepared to believe I have - I'm a php novice.) I wonder, should there be any other text in the uploaded file like a doctype or html of any sort? Alternatively is it possible that Dreamweaver or Windows or Apache or the server itself are altering the uploaded file in any way?

Furthermore, there is no fake gallery_remote2.php file in my other site's installation (www.ruralramblings.co.uk) yet the fullscreen slideshow works fine. I wonder why this could be?

All suggestions will be extremely gratefully recieved

Hi paour, thanks for sticking with me - sorry my reply is a bit slow, I'm in the UK.

Your observations are indeed pretty puzzling. It's as though maybe the server isn't liking the 'header ()' function?

My sites are on 1and1 shared servers and regrettably they don't allow access to the apache error logs. They do offer a way of creating your own error logs for debugging php scripts. I added their code to the gallery_remote2.php script and nothing seemed to happen, certainly I was unable to find any error.csv generated by it.

Feeling inexplicably slightly more confident with my php, I then tried to use the header function to redirect to my blog's 404 page - to no avail.

I tried turning rewrite off within gallery to see if that helped, but that was pretty messy and ultimately unsuccessful.

Being a tenacious chap, I'm keen to try and get the bottom of this, but I suspect I may be at the stage where I need to try re-installing Gallery from scratch unless you can shed provide any further insights into my dilemma?

Kind regards
