Hi, I get the error below when clicking Send & Print.

The report's template False is wrong, please contact your administrator. Can not separate file to save as attachment because the report's template does not contains the attributes 'data-oe-model' and 'data-oe-id' on the div with 'article' classname.

Now, I generated one invoice perfectly. I log on a few weeks later to generate another invoice and get that error. Nothing has changed. I haven't been tampering. Just doing my work and coming back to do an invoice. I searched Google and it came back with results form 2018 and to add some code in somewhere to fix it. But they never say where to add it and I'm not a programmer anyway, so I don't know if the code will be relevant.

Anybody seen this before? Searches in this forum came up blank.
