I have an odd problem. I'm using Drupal 7 and an Omega subtheme. Within Views, I have a block defined and it works great - appears where it's supposed to all over the site - except when the URL has a "?page=" in it. Some possibly relevant info: clean_urls and pathauto enabled, Delta and Layout installed but no Deltas defined.
I discovered this when I created a page View (of a different content-type) that features the pager to scroll through the results. When using the pager it appends "?page=1", "?page=2", etc to the URL. I think it does it by default and from what I've read it seems to be difficult to change this. I could probably put up with the non-clean URLs but the bigger issue now is trying to work out why this results in my first view block not being rendered. I've tested it out by navigating to random pages on the site and appending the "?page=" to the URl and it's always the same result - the block view's not displayed.
Do you have any idea, or any pointer to where I should start looking?
