Side note to @pickplugins You can’t ask for admin access. You get that.
What you do not seem to understand is that you cannot ask for admin access at all. Do not do this: “Can you please go our forum and post a question about this. I can’t ask here for your site access here.”
If you do not get that, please consider removing your plugins from www.remarpro.com and distribute them and support them 100% on your own site. That way you can do what you like without getting www.remarpro.com in the loop.
Here are somethings you can try instead of resorting to that behavior.
There are many ways to get information you need and accessing the user’s site is not one of them. That’s going too far.
You get the idea.
Volunteer support is not easy. But these forums need to a safe place for all users, experienced or new. Accessing their system that way is a short cut that will get you into real trouble in these forums.
Again, if this is a problem for you then please consider removing your plugin from the www.remarpro.com site and hosting it on your own site. There is nothing wrong with that and on your own site you can offer support as you please.
