Prestashop 1.7.8 no backend access, but frontend works fine

[isdngirl]

Hello, I am having an issue where when trying to log on to backend it goes into a loop and nothing happens it goes to the screen like the attached. I enabled debug and no errors. I have deleted cache in the var folders and killed browser cache but nothing. I do no have any additional caching enabled. I have even tried to restore a few days back and still the same issue so it appears that something maybe had a problem awhile ago but since I left myself logged in I didnt see it and now I cant restore to where it was working. I havent installed anything for months, so Im not sure what could have caused the problem but here it is.  The theme I am using is a child theme of warehouse but even if i reset the theme to warehouse in the db it doesnt fix the issue.  The front end side is fine for clients and they are still making orders but I cant get in via backend. I can however see and access database with phpadmin. Being its becoming a very big headache, is there something else I can try?

 

Or is there a module that will allow me to move my client and product data over without having access to the production database? The onyl ones I find work by installing on BO of the data producing side which wont work if I cant get in.

The production is 1.7.8 but now my host only offers 1.7.8.8 so it would need to migrate to the new one at the same time without BO access on production.

 

thank you for any ideas in advance

enable debug to get the errer logs,

1.please check the config of webserver (maybe apache) ,make sure this not rewrite rules to redirect your url to a different url from shop_url (you can check in database)

2.try to clear cookie in browser

Hello thank you for your reply, I have checked those and removed all blocking in the http access but no luck. Reset all cache again on server and local disk and now I have clones the database which finally gives a  smarty error  Fatal error: Cannot redeclare smartyEscape() (previously declared in /home/lepetith/public_html/staging2/config/smarty.config.inc.php:65) in /home/lepetith/public_html/config/smarty.config.inc.php on line 82 but no idea how to reset or how it arrived like that. At this point I would be happy to find a tool or way to just move the client data and products  into a clean db but it seems all of the migration addons listed are needing access to the BO of the source file which I cant get to

You cant just ask hosting to restore backup? Host did not change PHP by any chance?

They said php level (7.3) didnt change, I backed up from the 17th which is as far back as the data restore goes and still has same, error. I guess because the problem arrives before but since I stayed logged in I wouldnt have noticed. I think I will just try to get a person to import it into a clean slate. It seems to complicated to get it back to a state where I can access it. The problem is the clients are still using it , I cant just cut it off. Thank you for your ideas
