Hi Otoman,
Thank you for the ideas and suggestions. I tried everything that you have suggested including a the removal of WampServer followed by a clean, new install. It really was time to do a fresh install.
However, despite the fresh install of WampServer 3.2.0, once I switch Apache to version 2.4.34, the curl errors in the php error log returned.
Changing back to Apache version 2.4.41 eliminated the errors and the curl extension appears to be working properly now. The idea for upgrading Apache was not mine. It came from this Stack Overflow thread, [

I really do appreciate the time and effort that you put into WampServer and want to thank you for your support. I hope that my very small contribution to resolving this issue might help someone else someday.
