The problem exists only in OC 2.3 and affects modules exported for Page Builder. We are going to release a new bugfix version that solves this problem. It will be available at the start of the upcoming week. For the moment you can disable the module to temporally get rid of the error.
Sorry for the troubles and thanks for the patience.
Nice! Thank you for you great and responsive support! And I have another problem with Brainy Filter extension on last and previous version of theme. Sorry, I will write here. When I turn caching on it stops work. I speak with developers and they said the problem may be because the query main_table.category_id is empty or something.
I see you release new version with fixed this bug, I have tested it and confirm, it fixed, big thank you for that! But what about bug with cache? It still present. I have speak today with with Brainy Filter extension developer team.
you did the replacement in the official version, not in the tmp. We replaced it in tmp.maxidoors.lv and not it does not give any error. It does not filter the results either, but works on refresh, so we suppose you should turn off the ajax filter and leave the page reload functionality.
