Yes, I found it very strange. Don’t know the reason why this happened, but this problem is related to Google more than the server in this case, cause you didn’t change the protocol (from HTTP to HTTPS).

Oh in this case, you could only go for the 2nd option, at first I thought you had a self hosted WordPress install.
Hope that can be useful or that any other user can contribute with something else here.

Hi, I can think of 2 things related to this:
1. Your .htaccess file that has some wrong code inside (if you want to correct this be very careful, or your site could be with the error 500 for good).
2. Some plugin can be the culprit. You could rename (temporarily) the directory wp-content/plugins/ to wp-content/plugins_old/ for example and then you could access your dashboard. If you change the name of the folder it will appear that there are no plugins installed in your WP until you rename it back.

Hi, the problem here is that your site’s article appears as if it needed HTTPS (SSL certificate) to be accessed.
You can do 2 things to correct this:
1. Buy and install an SSL certificate in your site, which also can help improve your site’s SEO.
2. Ask Google to re-crawl your site using the Google Webmasters Tools, here: https://www.google.com/webmasters/tools/submit-url but this process can take quite a while until your site is re indexed.
Also, check in your configuration that the access is set as https:// instead of https:// in your WordPress dashboard, section Settings -> General (you can also check this directly in the database, in the table wp_options).

This is a memory problem. I see your site uses 256 MB which would be enough for a simple WordPress install so the problem could be in your plugins or even the theme you are using.
If you can use more memory (this depends on the hosting) you could increase the memory reserved to WordPress adding this in the .htaccess file:
php_value memory_limit 384M
in case you can use 384 MB or more in your site (you can pick any number above 300 M to be sure).
Also check if you have any cache plugins still active (to deactivate all plugins at once you can rename temporarily the wp-includes/plugins/ folder, but I recommend this only if you feel confident manipulating the WordPress filesystem).
And last, but not least, delete cookies and temp files in your browser, it happened to me a couple of times that I got similar errors but the problem was that I was seeing cached content in my browser ?? .

In your database the referal_url field of the wp_dwpc_impressions table is set to not be NULL, and at the moment of adding a record you try to set this field for the new record to NULL.
I see two options to solve this:
1. Avoid setting ‘referal_url’ to NULL:
INSERT INTO wp_dwpc_impressions (id, text_id, filtered, time_created, wp_post_id, dwpc_visitor_id, dwpc_last_impression_id, ip_address, impression_url, referal_url) VALUES (NULL, ‘ogTxAFr’, ‘0’, ‘2016-01-17 23:42:14’, ‘0’, ‘0’, ‘32129’, ‘73.200.219.200’, ‘https://mpjj.pw/&#8217;, NULL) <- This value NULL shouldn’t be actually NULL.
2. Access your database (you can do it via phpMyAdmin or any other database client) and modify the field ‘referal_url’ so it can hold a NULL value. For this you can use the following query in the SQL console for your database:
ALTER TABLE wp_dwpc_impressions MODIFY referal_url VARCHAR(200) NULL;
