Extension issues on Custom Module

[NunoDias]

Hey Bros & Sis,

Hope any one can help me with this issue. 🙏🏼

I believe that´s a simple fix, but, only for those how already know. 😀
Maybe You already faced this or a similar problem and can guide me through

I´ve tried to find by Googling but with no luck.
I´ve checked the Roles and everything seems to be ok.
I don´t know if it´s related or not, but, i believe this issue appeared after applying an SSL to the website, could be a coincidence. 🤔

Issue: https://lambdagolf.com/index.php/lambdaslideshow/adminhtml_lambdarevolution/
Accessing any extension on the module gives a 404 page.

I´ve attached the error.
Thank you for taking your time, and help a Brother. ❤️👍

Hi Rakesh,

Thank you for helping me out.

Deleted the var/cache, but i don´t have any var/session in the folder.

The problem, still remains.
Any other ideia?

Thanks for your efforts.
