I'm using T3 Framework 3.2.3 and T3 bs3 blank 2.2.3 on Joomla 5.3.0. I get a javascript error on the Template Styles admin area that prevents me from making any changes there, such as custom code, layout, theme, assignment etc. The following error occurs in the console when template styles admin page loads, then when I try to save anything the following error shows in the console.
I see that you state T3 will be supported for Joomla5. But there also appears to be mixed information contradicting this. Will you continue to support for Joomla 5 and 6 and beyond?
