I almost broke my head over this… Is this a bug or it just makes sense?
Revo install folder: /public_html/revo
Using friendly URLs (resource aliases).
Example of a resource with alias: https://mysite.org/revo/page1
If I have the above-mentioned checkbox unchecked for the resource (field
modx_site_content table), going to that URL ends up in a 404 page.
If I have the checkbox checked (isFolder = 1), I get a ‘/’ attached to the URL (i.e. https://mysite.org/revo/page1/) and the right page shows up.
