Custom template failing

Hi there,

I have been having a problem on 2 websites where I have custom templates and everything works fine, until suddenly the templates just stop working and my galleries only show 1″ square thumbnails.

I’m running the lastest version of Nextgen Gallery on all sites.

I’ve disabled all plugins, changed to the basic default WP theme, cleared my cache and nothing helps.

The first time it happened clearing the cache eventually fixed it, but this time its happened to 2 sites and I can’t figure out what is wrong.

The pages in question are for 2 escort agencies so I’m reluctant to post the links here.

Does anyone have any idea what could be wrong?

Thanks
Sean
