Hi, 

We have replied to your ticket. Please reply to it, so we can help you.

The Core plugin can not be uninstalled if any other our plugin is installed.

Waiting for your reply !

Can not be deinstalled when there is no your products.
I pointed out that as information that can help to solve problem.

Your support solves this problem 4 days. I tried to speed up. I sent screenshots, gave access to the 2 websites, sent xml files, uninstall all other plugin(only ajaxFilter stayed), reinstall ajaxFilter, restart app, download new Core set and seend on website    and get an answer to abuse them. Terrible customer relationship.
You spoil. 4 days my 2 project waiting and just get an answer to the question that I did not asked.

Hi Vedran,

I understand your frustration but what you say is not quite true and since I don't what you to mislead our customers reading this I will show some of the facts here.
You have submitted your initial support request 2 days ago on 19/04/2016. We have replied immediately on 19th and then on 20th we have replied 4 more times. Please note that we guarantee 24 hours response time and we have replied to you 5 times for these 24 hours. Today 21st we have replied 3 more times and we found what the problem was. I don't want to comment if this is bad or good support as I believe everyone can decide for himself.

Regarding the actual issue.

The customer complained that he doesn't see the Widget Zone in the administration of the Ajax Filters plugin, which prevent him to integrate the plugin in his website.
Initially we though the problem was related to either a missing SupportedWidgetZones.xml file or not having proper permissions, which turn out not to be the problem.
Today the customer provided FTP access and we found out the SupportedWidgetZones.xml is renamed to be with lowercase - supportedwidgetzones.xml. That is why the widget zones were not found and loaded in the administration of the plugin. So if anyone has the same problem please make sure you have not renamed the supplied files as this may have some side effects and could break the functionality of the product.
