"406 Not Acceptable" Error

[leonb]

We had coppermine install for few years know but we are getting the following error when creating and then trying to access a new file(minibrowser_1php)

406

Not Acceptable
An appropriate representation of the requested resource /photos/minibrowser_1.php could not be found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Thank you

minibrowser_1.php is not part of the coppermine package. To tell you more, you'd have to do as suggested in board rules and posting rules: you'd have to post a link to your gallery for a start.

you're running cpg1.4.18, update to the actual latest stable version (cpg1.4.21)

test.php is not part of coppermine. minibrowser_1.php is not part of coppermine. What you're talking about is invalid: if you get error messages when running files that don't come with coppermine, then ask the person who created those files. Post your actual coppermine-related issues here only.
And of course you definitely should do as François suggested.
