Since I recovered from some mess that I was having after upgrading my Ubuntu server to 14.04, the two Wordpress websites that I have hosted on the server have been randomly displaying the following error message upon opening:
Abort class-pclzip.php : Missing zlib extensions
The strange thing is that a refresh gets rid of the message. While this works for me, it's not a good idea to rely on guest visitor's quick-wittedness.
So, could you help me figure out what's missing and how to add it?
Thank you!
