Hi web54,

I once had a problem with the JoomShaper OnePage template being 'blocked' - what I did was open the Template in Joomla and choose Save as Copy - then use the copy of the template, which can be edited!

[web54]

it does not work
tried to install on a fresh one, and 500 error ( speaking about helix II )

And what does the Apache log say?

Another method is the following:

rename your existing template to "bad" (file system)
reinstall your template
copy the following files to the freshly installed template (example from JoomShaper OnePage):
templateDetails.xml
css\bootstrap.min.css
css\template.css
css\presets\preset[x].css
images\service-bg.jpg
images\slider-arrow-left.png
images\slider-arrow-right.png
js\main.js
less\theme.less
If you get the error 'FAILED TO PARSE PASSED IN VARIABLE @preset', choose another preset and everything will be fine (hopefully)...
