Really, I thank you very much, your attention and help.
During this time, I try some that you indicate but I can't solve the issue, but, your attention and help... Really, thank you very much!!
Well, I am not thinking in this possible solution, thank you.
I disabled all plugins with a line in config.php, after this moment, I can access fine to my site.
I install the php file in my FTP, and after, in admincp, I import the xml.
Now appears Panjo product in Products and Plugins - Products, but in the options of admincp not appears Panjo to configure (and Panjo is enabled) but not appears in the options of admincp.
When you indicate:
"To remove panjo fully uninstall the xml first, then the php file"
If I uninstall the xml, is when I have the problem with Database.
.
If you don't want to remove it, then why did you do it in the first place. I only said to do that because it is what I thought you wanted if you don't, then don't remove it and with plugins disabled via config you should not have any errors but up to you
