Hi C5,
I cannot get to the dashboard: ERR_TOO_MANY_REDIRECTS

How did this happen?

I added a WELCOME/BIENVENUE landing page at 'mysite.com/wecome-bienvenue' where users could choose to enter the English site or the French site and via a button click to access either 'mysite.com/en' or 'mysite.com/fr' . (I did this by adding a new locale en_US, copying the en_CA tree to the en_US, created the page from the top-level page of the new locale, deleted all the other pages in the en_US locale, then set the default locale to en_US.) To my surprise it worked but the browser threw a not secure warning for
'mysite.com/welcome-bienvenue' as well showing only placeholders for images with a not secure content warning even though the SSL certificate is installed correctly.

Trying to fix that, I tried using mod-rewrite rules in the htaccess file (both with and without the pretty URLs mod rewrite already in the file) to no avail. The last thing I did before getting the ERR_TOO_MANY_REDIRECTS when trying to go to 'mysite.com/login' was to uncheck the 'only render at canonical URLs'.

BEFORE I managed to lock myself the dashboard, SEO and redirection page was set like this:
pretty URLs enabled
canonical URL and alternate canonical URL set to : https:mysite.com
only render at canonical URLS - checked
add canonical tag - checked

I can get to "https://mysite.com/welcome-bienvenue' and through that page to
'https://mysite.com/en' or 'https://mysite.com/fr' but not to 'https:mysite.com/login'
(I have tried every permutation with and without index.php, with and without https: trying to get to /login).

I am leery of editing the config.php file because I have already done enough damage.
Hopefully getting me back in is a simple edit somewhere.

Thanks in advance to anyone who can help.

Cheers,
Marc
