Question File uploads not working in Crypsis 4.0.6

I have been testing Kunena 4.0.6 using the Crypsis template on Joomla 3.4.4 which is on the Protostar template. It simply reports "File upload failed." - tested this with jpegs, pdfs and txt files. If I switch to the Blue Eagle template, the file uploads work.

I noticed the following messages in the console in Chrome when I attempt an upload:
Uncaught TypeError: Cannot read property 'H5Form' of null
d.validateField @ html5fallback.js:1m.event.dispatch @ jquery.min.js:4m.event.add.r.handle @ jquery.min.js:4
jquery.min.js:5

this is an old joomla bug and should be fixed:
github.com/joomla/joomla-cms/pull/2202

Have double checked that those changes reflect in the js files, and they do.

could you try to reupload protostar again.

I checked again on my lochalhost, its still working with protostar and crypsis. See no error messages.

I uninstalled Crypsis through the Kunena backend, then reinstalled Kunena via the Joomla extension manager to get a fresh copy of the template. I cleared the Joomla cache and the browsing history of Firefox and Chrome. Unfortunately I still get that error.

do you have extra enabled plugins, maybe one plugins is the problem.

Disabled all system plugins except those for Joomla and Kunena, and don't have any extra Kunena plugins. Unfortunately same result.

I did notice that Firefox gives a slightly different error message in the console:
"TypeError: d.form is null" in html5fallback.js file.

do you have admin tools installed? if yes then update it to the newest version.

I have the same issue here. Crypsis will not allow file uploads. Going back to Blue Eagle will allow attachment uploads. It appears to be something with the template and/or upload code specifically with Crypsis.

I do have AdminTools and it is the latest version...

I do have AdminTools and it is the latest version...

Which version? When you use Admin Tools 3.6.3, try again install Kunena 4.0.6.
