Keep headers/logos under 125 pixels high. It takes up valuable viewing space, especially for laptop users, that is best left for the good stuff to appear"above the fold" Take a cue from the big companies, simple logos done well say it all. This is our #1 pet peeve - screaming logos and headers!
Installing the fix hacked wordpress site Scan plugin will check all this for you, and alert you that you might have missed. It will also tell you that a user named"admin" exists. That is the administrative user name. If you desire, you can follow a link and find instructions for changing that name. I think that there is a strong password enough protection that is good, and there have been no attacks on the blogs that I run, since I followed these steps.
Don't make the mistake of thinking that why not check here your hosting company will have your back as far as WordPress copies go. Not always. It has been my experience hop over to these guys that the hosting company may or may not be doing backups, while they say that they do. Why take that kind of chance?
You first need to create a user with administrator rights before you can delete the default admin account. To do this go to your WordPress Dashboard and click on User -> Create New User. Then enter all of the information you will need to enter.
Make a note of your password! I recommend the free or paid version of the protected software *Roboform* to remember your passwords.
I prefer to use a WordPress plugin to get the work done. Make sure that the plugin you select is in a position to do backups, has restore and can replicate. Be sure that it is frequently updated to keep pace with all new versions of WordPress. There's absolutely not any use in backing up your data to a plugin that is out of date, and not working.
