Site URL: https://mountaintrailrv.com.au/ I have upgraded some pages of a website to Fluid Engine Blocks. There is a HTML created tab that I want at the top of the page that has stopped working after activating it. <div class="tabs-start"><h1></h1></div> <div class="tab-section">Dimensions</div> Is there an easy way of reverting back or do I have to re-build all of the pages from backups and not upgrade that particular section to maintain the HTML tabs? Any help will be appreciated!
