Image template error causing admin area to not load properly

Hi Have been editing one of the HTML templates, had a problem with single and double quotes in the template img content tag. Now when I go in to admin whenever I click on a page to edit the regions the page stops loading at the image field, does not load further than the label. This also prevents any further interaction with the content, save buttons etc all missing and fields below the image field label don't load. It also removes the top level navigation from the top of the admin area. Can't save the page and therefore presume the corrected, non-broken HTML is not being used. I assume runway has cached the error template rather than using the fixed one? I have tried re-uploading copy of database, visited the page in question whilst logged in and used 2 different browsers to rule out browser caching. Is there a solution to this please?

Tried republish all to no avail. If this is a cache issue how do I flush? Thanks
