Dear customer,

Could you please give us (to [email protected]) admin access to your site, by indicating the forum post link in your email subject. We'll look into your issue as soon as possible.

sorry, I do not like to give the admin credentials to anyone, you can just tell me which CSS file I can take to expand all and collapse all? I think that's the problem.
Thanks

Dear customer,

Unfortunately we can't say what has caused that issue without admin access. If it is possible,can you please provide us admin access? The problem might be caused by a conflict with other plugins and/or the theme installed to your website. In order to fix the issue we need to take a look at the code of the plugin. That is why we need admin access.
Here is our privacy statement: web-dorado.com/web-dorado-privacy-statement.html
So please feel free to share temporary admin credentials with us, which you can close right after the problem is solved.

the problem is the size, look at this new test:

Dear customer,

Yes, we have noticed it too. Can you please provide us a direct link to your administrator page so as we can log in?
