This plugin (and many others) will need some love before they're fully ready for 1.5.8. For now, just add customers on the storefront.
Thank you for the prompt reply, swguy.
Makes me feel really disheartened, though. It started with the hosting provider only supporting pHp8.0 and up from beginning October.
I had to fix a lot of errors on my v155 store in order to get it working. It is still running at the moment, albeit shakily. However, the amount of error logs created every day is just crazy, so I decided to upgrade to v157.
The v157 upgrade caused a lot of database integration problems though. (I did not perform the steps in the best order).
So this week I decided to start over (as per your suggestions). Then I discovered v158 was released. In order to buy some extra time until the next forced pHp upgrade, I decided to give it a go. Now, after many hours of work, I realize that many plugins will need an update before being compatible (e.g. due to different language file convention).
Unfortunately, after 10 years we have learnt to rely heavily on some plugins in order to get the work done in a sufficient way on a daily basis...
Seems I will have to start again on v157, hopefully encountering less integration problems.
Wish I knew about all this before I started...
