I have a WHMCS module that another programmer has made (he has disappeared though :-( ) and now the module has a problem.
It doesn't seem to save its data properly to the database.
This is because WHCMS went the 'old' formatting to markup, that's what seems to need the fix to make it work again.
I think it's only storing retrieving and using the proper markup that is the issue.
(and possibly a quick check if all code is phpv7.x perfect too :-) )
Any rough idea of costs/hours???/
It's a fairly simple addon, but if it's not working it is useless ;-)
PS If you do not have the proper WHCMS experience, please do not apply.
