  • Themler theme modules are not enabled: "Billion Themler" and "Billion Themler Preview"

Cannot select controls in Themler preview area

Possible reasons:

  • Enabled "Smart cache for CSS" under ADVANCED PARAMETERS >> PERFORMANCE >> CCC
  • Disabled overrides under PrestaShop Admin Panel >> ADVANCED PARAMETERS >> PERFORMANCE

  • Selected "Never recompile template files" under ADVANCED PARAMETERS >> PERFORMANCE >> SMARTY. Please use either

    • "Recompile templates if the files have been updated" or

ADVANCED PARAMETERS >> PERFORMANCE >> CCC

  • Smart cache for CSS
  • Smart cache for JavaScript

This will increase the size of the theme folder and may cause memory problems while working with the theme in Themler (with saving, downloading, etc.).

It is better to disable these options while working with the theme in Themler.
