I'm wondering how you deleted the blogs,

Did you do it from the dashboard not the database?
If you did it from the dashboard the database may have become corrupted. You can check the IDs of the blogs in the dashboard > global and then you can check the database to see if they are the same.

I know this isn't a solution but it may help.

Just had a look at the file, some sort of cache creator maybe. You can also try and empty the caches under system > maintenance and do other repair like jobs there.

Hope you get this sorted soon

All the best

Hi @vitalemedia,

I guess that error is in your front-office. The problem could be in the "Random photo" widget, because it is set by default to load pictures from blog 4, but that blog doesn't exists anymore. So, you should just disable it or change the value of the "Blogs" parameter.

Regards!

@mgsolipa can you please make sure that in future versions the widget doesn't bug if the target blog is not found. It should display the block title and then a simple text like "Target collection #4 not found."
