So, the calendar was working wonderfully, but suddenly it has stopped. This guide will help you get it functioning again.
Rest assured that the calendar will never stop working on its own. If the calendar suddenly stopped working, something has changed on the server to cause this to happen. Example changes include PHP being upgraded, server/PHP configuration changes and the calendar files being uploaded/restored in non-binary mode.
No matter the reason for the calendar to stop working*, follow the steps below to fix your issue(s).
IMPORTANT! All calendar files must be uploaded in forced binary mode. See: http://www.easyphpcalendar.com/binaryMode.php
**If the calendar is working but you see a license key error, please skip to the License Errors section below.
1) Download the tester script from the Support Page.
2) Unzip and upload the tester directory to your server then open it in your browser.
3) Follow the instructions in the tester script for the calendar version that you have installed.
4) Download the calendar files as recommended by the tester script for your server. If your server does not pass the tests, you should contact your web host provider and tell them that something they have recently changed has broken your ability to run a script that requires Zend Optimizer, Zend Guard, or ionCube loaders. They will need to resolve this issue before you can continue. Usually, once they fix this issue, the calendar will function once again. If it doesn't, start this troubleshooting process over again.
5) Follow the Upgrade section of the instructions to upload the calendar files to your server. Links for the instructions are: Version 6 | Version 7
License Errors:
At this point, the calendar should be functioning. However if you see a license error, while viewing the calendar, click the Help link in the license error message and follow the instructions to update the license key.
* If you have moved the calendar installation and you are using Version 6, please also review the FAQ Server Path Issues.
