Hi pedrolaxe, you said that you updated to 1.4 and pagination was still broken?
Please can you try this:
1. Go to Settings > Reading > Blog Pages show at most > set it to 1
2. Now go to WP Catalogue > Settings > Pagination > set it how you want
3. Test now…. does this fix the pagination?
Another user reported that if the WP option in Settings > Reading > Blog Pages show at most, is bigger than the plugin option WP Catalogue > Settings > Pagination, then the permalink isn’t showing the pagination or pagination breaks.
We have 4 posts in the same category
“BLOG PAGES SHOW AT MOST = 10”
“PAGINATION = 2”
Permalink breaks: my_site_url/wpccategories/somecategory/page/2/
But if you set “BLOG PAGES SHOW AT MOST = 1(or 2 or 3)” the permalink works fine.
…working on fixing this… but just want to see if this is actually the issue on your site
