Zend Optimizer Not Installed... but it is.
We bought and installed the calendar nearly 2 months ago. Until last week, everything had been working wonderfully. Early last week, I got reports that the error message "Zend Optimizer Not Installed" had was appearing in place of all of the content on each of the pages where our calendars appear. I reviewed this website and found this article: https://www.easyphpcalendar.com/supp...kbarticleid=55
, which indicates that the problem lies on the server end.
Armed with this information, I contacted our hosting provider, gave them the information, and asked them to have a look. After some time, they called to let me know that they had checked everything out, determined that Zend Optimizer IS
installed and working correctly, that all of the other issues in the above article checked out fine, and that the problem must be with the calendar files.
Skeptical, I reinstalled the calendar on Friday, April 22nd and got everything working like it should. All appeared to be fine. Yesterday afternoon, everything was still working and I was able to add event information to the calendars as normal.
This morning I got a call from our provider to let me know that the error had reappeared. I explained to them that I had reinstalled the calendar and everything was working as of yesterday afternoon.
So, I need help. Why is my calendar failing now, after running perfectly for nearly 2 months?
