Qphoria CMS - invalid token when inserting image

Hope someone can help with this (Q - are you there?)!
When my customer edits a CMS article (OC 1.4.8b) and tries to insert an image into the CKeditor window, they get an OC login window appear requesting they log in to OC again - 'Invalid token details' is displayed. If they then log in again, then all continues as it should and they can insert the image. Next time they try to insert an image the same thing happens.

If I log in as Top Admin, I don't get this problem.

If the customer tries to insert an image in the Information module, or any other use of FCKeditor, all works fine - seems this is a 'feature' of CMS.

Help!!

ok get new version from my site

Hi Q - thanks for the response. Do you mean the one that's there right now? Presumably you know the source of this error? I'd be interested to understand as I'm trying to gain a deeper insight into the workings of OC...

Yes..its fixed. Get the latest version from your account download page on my site and reupload the files. There was a token change made for 1.4.8 that I forgot to add to the mod.

Ok, I've downloaded the new version and uploaded the files. Now when I go to edit a category or article, I just get a blank screen.
Is this caused by something I've missed?

Get latest again. had a typo

Nice work Q - and quick too. Thank you - it all works fine now.
