@stiofan,
I think it would be fair if the author will publish the Business Hour addon for GDv1 on github as open source. The availability of GDv2 and all functionality will take still a couple of months and a page migration process will for me also take some additional months.
I have to make changes on the addon as this is not PHP >=7.1 compatible for me (using V1.3.7.5 – I know that there is a newer one but this is breaking my detail pages) and I have to update PHP7.0 for my page soon. PHP7.0 will end of active support at the end of the year and my plan is to switch to a higher version around mid of the year.
BTW: I contacted the author about the issues I have with the addon but never got a reply.
Could you contact the author or should I do?
Best,
Dirk
