Event onContentAfterTitle only accepts String results.

The issue is not with Virtuemart. It's with content plugin SP Page Builder.
If there is no article id, the plugin return false, it should return an empty string instead.
The fall back return should also return an empty space.

The error is triggered when you use virtuemart because the content plugins are triggered and there is no 'ID' attibute to the $article being passed. Virtuemart uses virtuemart_product_id instead.

Never the less, change your content plugin with this simple fix. You will save headaches to many customers.

Problem is still occuring on SP Page Builder 5.4.6

Hi Ofi, I have updated our test website to the latest Page Builder, VirtueMart and Joomla (plus some others), enabled the Joomla Plug again on VirtueMart and the error is now present again, when you clikc on the SHOP menu.

Hopefully this can now be resolved given the insights by Jeremy Magne

Thanks

Jamie

Hi Ofi, I DO NOT authorise taking a copy of the website, there is a lot of personal information, and I don't want this going elsewhere. Please only debug / experiment on this site, it's a TEST Site for us and not productive, so you can play with it.

@jamie, @Ofi
In the code of SP Page Builder content plugin.
The error is clear and simple :
Event onContentAfterTitle only accepts String results.

Your plugin returns a Boolean

Line 248:
replace return false;
by return '';

Line 264:
replace return false;
by return '';

Version 5.5.2 was released and your plugin still crashes.
When will you fix the function onContentAfterTitle in YOUR plugin ?
This is not n issue with Virtuemart it's an issuer with SP Pagew Builder content plugin.

the function onContentAfterTitle should retur a string but your plugin returns a boolean.

You have been given the fix many times but your are still not fixing it...
