Support

 hi, yestoday I moved my website to a new hosting server, everything (seems) works fine. Of course I had not login in frontend yet since I am busy on something else. Other people can not visit my website because I had not told them the new domain name.

Last night, I login in the backend , yes, I can login in at that time, though I had Admin Tools installed a long time ago.

Then I noticed that Admin Tools has new updates. Ok, I installed the updates and upgraded to Admin Tools Pro v3.6.7.

Next, I made whole website backup with Akeeba Backup (also upgraded to the latest version last night).

Next , I went to bed since it was too late.

Today, I read news that Joomla 3.4.7 was released. So I decided to update my Joomla core ASAP. But, now the problem comes:

I can see the backend login page when I visit the secure login URL like:

https://www.mydomain.com/administrator/?mysecretcode

I input the username and password, yes, my Super User account, as usual.

Then after I click "login" button, the login page just refreshed and I am still out of my website backend!

Well, I thought I was blocked by Admin Tools. So I use FTP to changed the filename of Admin Tools plugin from main.php to main-disable.php, just like the doc said.

Then I tried again. Nothing changed.

I went to website frontend, tried to login as Super User, the same thing happened: after I click the "login" button, the page just refreshed, I can not login in!

I am sure I did not forgot my suername or password, because last night I can login in, I even had upgraded my Admin Tools!

I tried to manually edit the /configuration.php, set error reporting as:

	public $error_reporting = 'maximum';

Then I tried again both backend and frontend login, nothing reported as error or warning. Just the page refreshed!

This is too wierd , so I have to ask for help from you. Hope you will help me to solve this.

Thank you!

Some updates:

I asked a registered user on my website to test it:

When he tried to login from the frontpage login form (by mod_bt_login), the page refreshed after he click "login" button, he can not login in.

Then he went to the forum page (com_kunena), input account data to the login form of Kunena forum component, then he clicked "login" button, the result is:

Error 404 can not find component

The URL of that page was:

https://www.joomlagate.com/index.php?option=com_kunena&view=home&defaultmenu=155&Itemid=154

Please notice that in the URL, all amp symbols were converted to HTML entity - oh no, your forum converted them again, so please look at the attached screenshot.



I think this problem is very weird , because I WAS able to login in the backend last night, though I did not test the frontend yestoday.

Hope you will find the cause. Thank you.

I can not add image attachment when I tried to edit my former post.

Ok, I recall that there is one more thing I did after I upgrade Admin Tools: I changed the SSL certificate for my domain.

Yestoday I was using the self-signed SSL certificate generated by my VestaCP panel itself. It can work but always show warning like "invalid certificate". So this morning I applied for a free SSL certificate then used it.

Maybe my server (built by myself with VestaCP) was not correctly configured to use the new certificate.

If you have sme experience on this , please give me some hints.

Thank you.

I just checked with FTP that both cookie_domain and cookie_path in the configuration.php are empty.

Then I login in to my VestaCP panel, and changed the SSL certificate to use the one generated by my VestaCP (openssl) . Then I close Chrome browser and restart it to clear browser cache, then I re-open my backend login page (of course Chrome warned me about the certificate and I choose to open it anyway), tried again, still can not login in, without any error displaying, just a "plain and peaceful loop".

This is very weird. I can not though about any reason and any solution to it!

hi, my friend, you are right!

Your "session" word reminded me. I have forgotten to tell you about this: since this is a new VPS, I installed VestaCP to manage it myself. I am also nearly a newbie of server configuration.

Yes today I installed "memcache" for this server, then I followed some tutorial on internet to set the Joomla configuration.php from:

	public $session_handler = 'database';

to

	public $session_handler = 'memcache';

This changed prevented me to login in.

Now I changed that value to "database" again, I can login in now!

Thank you.

It seems that I still know nothing about memcache. I need study more. If you have some experience about session handling with memcache, please do not hesitate to teach me.

Thank you again!
