PHP Contact form with image verification
This is how the form will look like, this is just an image, you can download the finished files at the end of this page.
If you use a normal contact form then spammers will find a way to automatically send junk messages through that form, so you need a way to verify that the sender is an actual person and not an automated script.
A good solution for this is to use an random code that is generated by a script the code will be displayed as an image so only a person could read the image and type the number. This practice is called Captcha image validation. The image also has a noise added to avoid any existent automated scripts that could read the text from the image.
The contact form also makes sure the user filled all the form fields correctly, when all fields are completed and the text entered inside email box is an email address.
The form will contain a link to an image, the link to image is actually a link to a php file generating the image, user will have to fill the image code inside a form field once with the other message contents (subject, sender email, etc) then click submit, if the code in the image will not be correct then message is not sent and user is asked to fill the image code again, the other form fields remain filled.
When form is submitted the data is send to this script that verifies the image code and the email is sent or the user is sent back to fill the form again.

Why I Can not login via wp-admin but same time I can login from WP-login.php
I know how it feel, like no one know the solution. You like to pay everything you have, to find out why you can not login into your wordpress from wp-admin. And if you do it will redirect to same page without showing any message. but same time you can login into your wordpress from wp-login.php. Sometime clearing the browser’s cookies might let us login again but to be honest it’s a pain, and clearing your cookies isn’t a permanent fix and do not work everyone.
Answer is easy when you know the following two solutions.
Solution1: At WordPress admin–> Settings–> General Settings:
“WordPress address (URL)” should be same as “Blog address (URL)”
Solution2: Fixing issue with cookies.
problem is that occasionally on our various WordPress sites the wp-admin.php URL login stops working and we can only login through wp-login.php.
What we need to do is to force WordPress to follow the correct cookie path. This can be done by adding a small line of code to the wp-config.php file located in your WordPress installation root directory.
Open up wp-config.php in your web editor and add this:
If you’re unsure, it can go just before the ?> at the end of the php code like so:
Update: Some reported WP Security Scan case this issue. Please test and confirm in comments if you are using WP Security Scan wordpress plugin.

Alternative Cron
Use this, for example, if scheduled posts are not getting published.
"this alternate method uses a redirection approach,
which makes the users browser get a redirect when the cron needs to run,
so that they come back to the site immediately while cron
continues to run in the connection they just dropped.
This method is a bit iffy sometimes, which is why it's not the default."
