Tips:
Are you updating the templates in the correct way?
If you update the template files in the modules/modulename/templates/blocks/ folder, then the answer is no.
Depending on your XOOPS version, AND the original version used to create the XOOPS site, you need to either edit the templates in the database through the system admin -> templates section (clone the default template set first, you cannot edit the default template set, and edit the cloned set. set the active template set in the system admin -> preferences -> general settings page),
or, if your site was built from XOOPS 2.0.14 from the ground up, you can override the templates via your theme by adding the edited templates to the themes/yourcurrentthemename/modules/modulename/blocks/ folder (you'll have to create the path from your theme folder). There is a good description on how to override templates announced in the news.
Hope this helps.
