App Store Header icons missing

Although I previously followed the procedure above, I repeated it as suggested without desired results. Thank you for the suggestions. The same is true in Normal Mode. If I uninstall the app store app, can it be downloaded again? Could it be that I will be forced to update High Sierra to Mojave?

New OS installed from bootable drive. Still no icons in App Store and have additional issue with Safari and websites loading. (I exported Book Marks before install and imported them back into Safari favorites)

(1) Safari Can't Connect to Server, most often when I select a link within an email to go to a page. (Example: Received email My electric bill statement was ready. Clicking on the link to go to their page resulted in Safari message Safari can't connect to Server. The site loads correctly when accessing with bookmark in favorites. After loggin off again got the Safari message) (2) When select some of the favorites to go to the website all but three of them load correctly. One of the loads the Safari Can't connect... the other two reroute to Azotel Outside site. (One of those is Apple.com) TO TOP THINGS OFF: THIS IT TRUE OF ALL MACS ON OUR WiFi Airport extreme network . I have never heard of Azotel and the search for it's website for info, won't load because Safari can't connect. I got an email from our ISP yesterday after I finished getting back on line that they are in the process of upgrades on their towers and on servers...I am starting to wonder if the problem mght not be local. When the errors started I had forgotten that Shortly after 11 pm on the 19th the internet went down and when I got up on the 20th the internet was still down about 7:30 AM The ISP tech support had me attempted to connect to by having me connect to the POE supply with my MacBook by ethernet with the MAC Address. I was told I needed a new power supply and someone would be out. I received a text from the owner shortly after noon I should be up but no explanation. Another email today to expect short periodic interruption. I went on line with Firefox and the same sites do not load on it either.

Beyond trying to resolve the Can't load issues, I going to wait for the ISP to work their bugs out.

Have you ever heard of Azotel? A short time ago I also got a message the same log in page for them when logging in after restart for the WiFi.

Thank for the INFO...The etrecheck is being hijacked by Azotel. When I respond to "verify my email" on the pastebin user set up Safari can't find server... I was using malwarbytes prior to this starting but did not download again after the OS reinstall. At this point I would be happy to get rid of Azotel. ISP sent me email that Azotel is used for remote log in to their email server from the internet and he has no idea why the certificate is in my system. (KNOWN him for years and he's all Microsoft, well, except his email was "sent from my iPhone") Still treading water and no leaks in the preserver yet" HaHa.

I tried the entrecheck from firefox and go security error but I my email verification for pastebin sent through. Security Error Attached: The Tracer Route was

@ Mr. Hoffman & BD Aqua: Reading both your comments gave me the Idea to verify and compare IP and MAC address for the Network connection. My ISP is www.techstream.net in Pine Bluff Arkansas. 

I entered them in the address bar of Safari, Firefox, & Google Chrome with the same result. When I enter www.Techstream.net & Azotel prefixes Techstream in the address bar and reroutes to Azotel. 

I did a Google Search in Firefox and Techstream's site info come up, but select the main website, support, residential plans or business plans and each is rerouted to Azotel. 

I believe it possible when I gave my MAC address on my MacBook to Tech Support & he used it attempting to connect to our radio it added the MacBook MAC Address to TechStream's network path for our account...I know the MAC Address of our Airport Express is used for communication with our network over their radio transceiver on the roof that communicates with their tower about 2 miles away. 

So, I took screen shots of the WiFi Network Info then went to Airport Utility and looked at my MacBook. Same IP and MAC Address. Checked MAC Address of Airport Extreme Not the same as WiFi Network Info.

If I am on the correct PATH. I need to contact Techstream to have my the Network info IP and MAC changed to the Airport Express. In Hind sight, I never remember Tech support wanting the MAC Address of one of my computers to connect to the ISP..

BTW I selected the Link to TechStream.net in the first line and it routed me to Azotel. Request you see if it will load correctly from your end.

Yes, confirm: Logged out of the App Store, and back in again. Also tried the Mac App Store while in Safe Mode.

Just finished creating a new adminstator account using my wife name and email accounts... both in normal and safe modes App Store still no icons.

I do have an anti-malware "Malwarebytes/free" that I used for several years without issues and for over two years I have been using "Clean My Mac" that has cleaner and optimizers; which also has seemed not an issue. The only firewall used is the one in "security and privacy" in system preferences. The Malwarebytes has shown clean scans for several months. The Clean My Mac log shows it was run on Saturday 7/13/19 at 22:47.

I have iMac doing time machine back ups...I tried obtaining High Sierra from withThe App Store Application, but when I search High Sierra download Nothing comes up. Without the tool bar icons seems I am unable to access my account except for the settings: Nothing else including downloads & Purchases. Can I restore the Operating System from time machine with a back up from BEFORE the 15th when the issue started?

Thank You...Yesterday I went uninstalled ALL anti-malware, cleaner, & Gemini 2 duplicate finder. I had several "NON NATIVE" other Bible Reference apps, so got rid of them as well. I will try the direct to download first, but I have 16 GB Flash drive I erased and formatted to Mac OS Extended to build a bootable drive from my wife's MacBook Air as second option.
