Steps I have tried to fix the problem:

None yet, asI have no clue what I could have done to trigger this error

2

Try deleting everything in your
/var/cache/
folder

3

@techbill Thank you for your feedback!
Unfortunately deleting the cache did not help.

4

I hope you did not delete the /var/cache/ but what is inside the /cache/ folder. If you deleted the /cache/ itself then recreate the cache folder again and set the permission on it.

Did you enable or edit any widget etc?

5

I actually renamed the /cache/ folder and a new /cache/ folder recreated itself within seconds.

I added an e-mail-related widget to the dashboard today but thought that I had already removed it because it did not show what I expected.

Just to be clear - I can access all pages in Mautic besides the dashboard. If I click on [Dashoard] in the navigation it does not load and if I manually add “/s/dashboard” to my mautic domain I get a “500 Internal Server Error” …

6

Reason I asked about widget because your error seem very similar to this one reported over at Mautic crashed: internal server error after editing dashboard "Best email read hours" widget · Issue #10640 · mautic/mautic · GitHub

@techbill - THANK YOU A LOT for pointing me to that topic.

Changing …

a:4:{s:10:“timeFormat”;N;s:9:“companyId”;s:0:“”;s:10:“campaignId”;N;s:9:“segmentId”;i:148;}

… to …

a:0:{}

… did the trick. My dashboard works again :+1:
