Hi, many thanks for the reply.
Yes it was an issue caused by the theme.
For reference, it was solved by installing the following;

Many thanks
Thank you Steven – that has worked perfectly.
Looks like 5.5 was to blame! (/ running a theme with old code ..)
Cheers
Same issue here – can’t initially find a plug in that’s causing the issue.
Table sets to load but just shows the thick lines from the header & footer.
Any ideas?
