Hello Toufiq,
Nice speech about using a staging. Somthing I normaly do but in this case totaly irrlevant because this is only a default joomla site with the Helix temaplate and comming soon active. Nothing else.
Joomla is and was up-2-date, Helix I updated. If I make this in staging then it will be an exactly copy with the same result.
You can reproduce it as follow:
- Login at the backend
- Settings in the helix template you can't save. You will see an enless route.
- Go to the frondend and you will see also and error
- If logout in the administrator part, you will see the correct page.
As far as I can see Helix is doing something wrong with the user crediential check. This has been proven by:
- Loged-in on the backend goto the frondend and give an error.
- Loged-in on the backend goto to the helix settings. This will also give an error in Helix preview.
- If you logout the page is visible on the frontend.
Hope this makes it more clear.
