I have the same problem by trying to load the page builder. The name of the site is “mamazone.bg”
The theme is “Trendo”. It is just installed on the site. Would you tell me what I have to do, to receive support from you – what additional information you need?
Thank you in advance!
Sorry, but this error is in no way connected to BurnEngine/Trendo. It is a common bug in OpenCart 126.96.36.199 (which you’re currently using) and would appear on any other theme too. We have removed the error (which is usually not included in our free support), but you are advised to upgrade to a more recent OpenCart version (188.8.131.52 at least) as there are certainly more bugs to come.
