Hello,
Commercial themes are officially not supported here, but I’m familiar with the Xstore theme you’re using, and this should be quite easy to fix.
Just go to SETTINGS => PERMALINKS, scroll down to the section marked below and change the “Portfolio Base” to something more appropriate (like model, models, etc). Optionally, you could also change the “Portfolio Category Base” as well. When you’re done, scroll all the way down and click on SAVE CHANGES.

Hello George,
I do appreciate your help, thank you.
I have tried to modify my portfolios name through this process, and it works (I’ve replaced “project”, which is the name of the portfolios), by “models” already, however, my website is in 2 languages, and what I would like is to name my portfolios differently according to the language selected.
I use WPML as well, so do you think I have a solution ?
Thank you,
Regards,
Siham
Hello,
As you’re using WPLM for your translation, kindly see if this post on the WPML support forums helps you:
https://wpml.org/forums/topic/translate-custom-post-type-permalink-slug-created-with-wck-plugin/
If it doesn’t work, I’ll advise you post in the WPML forums for help, as I’m not familiar with WPML and can’t be of much help with this.
Good luck!
I’ll do that, thank you for your help.
