Since Theme Magic uses LESS files to make the real time changes to the design, I thought the issue maybe related Admintools htaccess rules preventing the loading of LESS files. I have added less to the list of back-end and front-end file types allowed in select directories.
I also went to Components > Admin Tools > Web Application Firewall > Configure WAF > Visual Fingerprinting Protection and set "Allow Site Templates" to "Yes"
It still won't load and I get a 404 - Component not found.
Not really sure what else to try an modify within Admintools so that Thememagic and MegaMenu will load.
Thanks in advance for any suggestions.
