Hello there!
So, to give a bit of more info of the possible reason for such an error :
- An issue with one of the image, which is breaking php scripts runned by iCagenda (a corrupted image breaking thumbnail generator script)
- An issue with dates setting, too long period with weekdays selected, and server too slow to work well with too much data.
- PHP version : php 7 is now the standard, which one is much more faster and performant than all php 5 versions.
- Too much events per page loaded (on a slow and not performant server, loading more than 100 events could give trouble)
If the issue only on the events list page, the best to know where the issue is related to the server php performance (not related to server memory directly, but the speed to process data even if one error somewhere...) :
- Disbale ALL events
- Check if events list page loads, with "no events" message.
- If it loads, then enable events ONE by ONE, until you have again this issue.
- You may found which event(s) could give a problem this way, and then check if due to date settings or event image.
My opinion: a too long period. Better to not set a period more than 2 years (why ? On fast performant server, you can do much more, but not on slow ones. And in 2 years (hope before of course) the new dates system will manage better very long period with more options more fluently even on slow server
)
Hope this helps ?
Best regards,
Cyril
