Look, 32bit stuff will not run on mac after Mojave.. PERIOD. Won't work with the 32bit wrappers either. Once you upgrade past OSX Mojave you will need to find alternative 64bit plugins to use. The wrappers will stop working and VEP6 will stop working too. I don't blame VSL for letting this go, its dead on the vine as a feature and hardly anyone needs 32bit plugins anymore, lots of work to keep it going.
Or you could run the 32bit version of VEP server on a windows box in order to host the windows version of the 32bit plugins, if you really must still use them.
In the meantime there are various work arounds..

also, there is NetVSTHost, which runs on Windows, but for now you can use it with Wine on a mac and actually host 32bit windows plugins on a mac and use them...its better then nothing...
PlogueBidule might have a solution too, I'm not sure.
