Wrapping blocks changes Block ID and Block Class.
Tested on 2 installations, everything is up to date.
On one of them, it also adds a removed Virtual Class to the block after wrapping.
Not sure what’s that triggering. Tested that behaviour with freshly inserted blocks as well.
Hi @Marius,
Indeed, I have been able to reproduce this issue on my end and can confirm it is a bug.
It seems a Virtual Class is added when link copied block is active.
Moving this to confirmed bugs.
Please bear with us while we find a fix for this.
Thank you for reporting this and sorry for the inconvenience.
Hello @Marius,
My apologies for the time it’s taken to get back to you about this issue.
This should be fixed in 1.2.9.7.
If you still encounter trouble with classes changing when wrapping them, I’d be grateful if you could let me know.
Thanks once again for the clear and concise report.
Cheers,
Thank you for addressing this @Louis. At first sight, everything looks fine.
Can’t wait to readapt again
