Hello Arnel,

The Joomla version is 3.1.5. It has no plug-ins at all so far, not even a 3th party template. Its a fresh installation. I used Softaculous to install it. I have an addon domain too though and it is working well. So, supposedly, the only difference with another fresh Joomla installation is the addon folder. I am going to install Joomla again but this time I will delete the folders manually making sure that nothing from the last installation remains. If this does not work I will be back with you. Thanks.

Arnel,
The installation worked fine after manually deleting the folders, but now the problem is that Joomla does not allow me to log in on the back end nor on the front end. Could you help me, please? Thanks.

Hello Perigono,

Sorry for the ongoing problems! Sounds like you're making progress though. I understand that you're working with latinface.com, but the best way to handle this is the manual method describe in the Joomla documentation here:

Recover or Reset your Admin Pasword

Since I do not know your password, then it would be better if you did the steps. You can use the cPanel File manager in place of an FTP client as they're suggesting in the instructions. That should allow you to recover the password.

Please let us know if you're still having any issues with the site.

Regards,
Arnel C.

Hello Arnel,
I found the cause of the log-in problem. My fault. The rule for setting up the username in Joomla is: No spaces, at least 2 characters and must not contain the following characters: < > \ " ' % ; ( ) &. My Username had two %. I had to get inside of the administration following the last option of the document you pointed out which was the only that worked. Once I was inside of the administration, I tried to write my username again and I received the warning. Since the username was established through Softaculous before installing Joomla, I never saw the warning. When I tried to login on the backend, I couldn't. Sounds logical?
Thank you very much for your help. I appreciate it.
perigono.
