Cannot log into Admin but do not get error

[martinbailey]

I installed Prestashop V1.4.7.0 yesterday without issue. I came back today to do more work on the site and could not log into Admin back office. It does not give me an error - it simply returns me back to the login page. The site is hosted with Heart Internet in the UK, who I host many sites with (Joomla powered) without problems.

 

I've researched these and other forums, and have so far tried the following:

 

1. Cleared browser cache in Chrome

2. Tried logging in using Firefox

3. Cleared the /tools/smarty/cache and /tools/smarty/compile folders

4. Removed the following from the /classes/cookie.php file:

 

AND (!isset($this->_content['remote_addr']) OR $this->_content['remote_addr'] == ip2long(Tools::getRemoteAddr()) OR !Configuration::get('PS_COOKIE_CHECKIP'))

 

5. Reduced the cookie expiry time (as apparently IE can have issues with longest time cookies) : inclasses/Cookie.php constructor,

 

set : $this->_expire = isset($expire) ? (int)($expire) : (time() + 3600);

 

6. Used an MD5 generator to create a new string (based on what I believed to be the password). The hash string was different to the one stored in the database. When I tried to log in it gave me an incorrect password message. I reverted it to the previous MD5 string

 

7. I tried to log in on a completely different computer. No luck.

 

In all browsers with clean cache I cannot log in.

 

This is extremely worrying given that this is my first experience of Presta Shop. I don't want to put in weeks or months of work to get this site live only to find that I can't log into it!

 

Can anyone offer advice on what else I can try?

Addendum:

 

I saw another post on here that suggested renaming the admin folder to something else, which I did. No luck...

i have same problem with you

 

did you find the solution?

[martinbailey]

I was running an older version - 1.4 x. I installed a fresh 1.5.x version and it has been fine since. A friend found forums suggesting it was a known issue with that version.

update: this cookie bug somehow fixed itself, after 2 days i can login again

Deleted a recent installation (latest version) from earlier today due to an unresolved issue and just tried installing it again twice and cannot login either. No error message shown.

Finally got in after running ccleaner and rebooting.
