If you are not pleased with the default border_portfolio and border_gallery URL slugs, we are giving out the chance of changing the project or gallery URL slugs, by following the next steps.
Step 1 — Changing the Portfolio Slug
From the WordPres Dashboard go to Settings→ PixTypes→ Enable Portfolio (checkbox)→ Change Single Item Slug→ New Single Item Slug→ Insert your new URL Slug;
Step 2 — Changing the Galleries Slug
From the WordPres Dashboard go to Settings→ PixTypes→ Enable Gallery (checkbox)→ Change Single Item Slug→ New Single Item Slug — Insert your new URL Slug;
Step 3 — Reflushing Permalinks
You can flush the permalinks (a piece of WordPress jargon) by accessing Settings→ Permalinks and pressing Save.
NOTE: You can’t remove these slugs, because, by having this part of the link is the only way WordPress can “understand” the element it is handling, is a project and not a simple page. As you can see, the pages don’t have anything between the base link address of the website and the title.
