I am using T3V3 version 2.1.6 with tpl_t3_bs3_blank. The problem is happen when I enable the development mode. The web page become not display or blank page. However when I disable the dev mode, the page back to normal display.
I tried to checking it on Title , then the result are 6 Errors, 4 warning(s). Below are the results :
