I'm sorry to hear that you are having trouble with your Showkase site.
I hope my notes below help.
If you try to view one of them directly in a browser (e.g. http://bobsgallery.digido.com/_themes/k … styles.css), you'll see the following error message:
You don't have permission to access this resource.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
Ask your web host if they have made any changes to your hosting account recently which might be contributing to the problem.
If they have made a change, then perhaps they can reverse it.
Here are some other suggestions...
First of all, please make a complete backup of your site, just in case anything goes wrong and you need to reinstate your original files at a later date. (Even though the site is not currently functioning, a backup might come in useful if you need to rebuild your site.)
Assuming you can log in and navigate around the interface without any CSS, go yo 'System -> Files' and click 'make writeable' against every entry. This should change the permissions throughout your site and might hopefully resolve your problem.
If you need to rebuild your site, there are a couple of things that you can do to reduce the workload.
(1) You can retain the Showkase settings from your original site by manually copying the following files and folders from your original site to your new site (overwriting the default versions which will be in place after a fresh install).
Do not copy the _data/pagesdata.txt file though, as this lists the pages present in each site (which will be different after a fresh install).
If you use a custom logo via an image stored in the library, for example, then you might also like to copy the _library folder from your original site to your new site.
If you have modified any Showakse source files or used the custom.css or custom.js files, then please remember that you will need to reinstate your customized files after a fresh install.
(2) You can import all the pages from your original site (via 'Site -> Import') to avoid having to recreate all your pages from scratch. You can import multiple pages at once so recreating your original site should be relatively quick and easy. (You'll need the page folders from your backup to do this.)
Just in case you need a new Showkase-Pro download link, I've emailed you a new one so you can downland the latest version (v1.7.5).
I am hopeful that your web host will be able to help you fix the problem quickly and without too much effort.
If you run into any difficulties trying to explain things to your web host, just ask them why trying to view this file: http://bobsgallery.digido.com/_themes/k … styles.css
I hope my notes help and point you in the right direction.
