DXMAPS is a free non-commercial site, funded through user donations and Google advertising. Without them the site would simply not exist.
If you are a regular user of DXMAPS you are kindly requested to become a supporter user or at least view the advertising.
If you have some kind of Ad blocker plugin / software that is preventing Google ads from being shown, then you will get a yellow warning message asking you to disable the Ad blocking for DXMAPS.COM service.
Some software that often cause the blocking of ads: AdBlock Plus, uBlock, MalwareBytes, AdBlock, etc.
If after enabling Ads for DXMAPS.COM in your Ad blocking software you still get the yellow warning message, that means without doubt that there is something else in your system that is also causing the blocking. It can be another software, the antivirus program, a modified HOST file or some configuration of your Internet browser. You also have more information about Ad blocking at Wikipedia.
As the blocking is made in YOUR computer. YOU and ONLY YOU can disable it, and it is up to YOU to find the way to do it. Do not waste you time contacting DXMAPS support with your complains about this issue because you will not even be answered.
The best I can do is to give you some ideas that have helped other users. If neither of them helps you then I am sorry but I can't do anything to help you.
In Firefox, you must disable Enhanced Tracking Protection for www.dxmaps.com.
In older versions of Firefox, go to the configuration options (type about:preferences#privacy in the address bar) and then in "Privacy and Security - Tracking protection" make sure that the "Use Tracking Protection to block know trackers" option is set to "Only in private windows" or "Never"
In Chrome, make sure that the the ad settings (type chrome://settings/content/ads in the address bar) are not preventing ads from being shown. More information.
If you use Bitdefender Anti-Tracker, you should also add www.dxmaps.com and dxmaps.com to the exceptions.
If you use the DuckDuckGo Privacy Essentials extension in your browser, you should also add www.dxmaps.com and dxmaps.com to the exceptions or disable that extension.
Look at the browser's console window: If after trying all the steps mentioned above you are still getting the yellow warning then it means that there is still some software or configuration option that is preventing Google ads from being viewed. In order to possibly get more information about who is causing the blocking you can have a look at the browser's console window while loading the DXMAPS page and see if any warnings are shown there that could give you some clue.
For most browser follow these steps:
The layout can be slightly different from one browser to another, but the concept is the same.
Remember that the blocking of Ads is made in YOUR computer. YOU and ONLY YOU can disable it, and it is up to YOU to find the way to do it. Do not waste you time contacting DXMAPS support with your complains about this issue because you will not even be answered.
If none of the above ideas has helped you then I am sorry but I can't do anything else. You will have to sort this issue yourself.
