No you are not the only member getting this code error, first of all I will advise you read this
thread by 1miau on how to draw tables using the BBcode.
The errors mostly varies so it depends on why you got yours, first it could be limit of bytes exceed and therefore cut the table into two. Secondly which I think might be the case for you is adding a character where there shouldn’t be in the code or opening a table with without closing or closing with properly opening anyone.
Just use the guide in the thread and check through your code again.
