About two weeks ago, my website has been hacked and infected by malware. Therefore, I had to take some steps to solve this problems. Because my website based on WordPress, so I took several steps, whicha are cleaning infeceted files on the website, cleans infected php code, change the admin password, and update all the plug-ins installed on the website. The last step (update all plug-ins) seems turns out cause an impact, because suddenly it always appear a pop-up “BlockUI requires jQuery V1.2.3 or later!” every time i open the dashboard of my website. It is not a big problem, but it is quite annoying.
Therefore I was looking for a way to eliminate this. And finally I found the most effective way to get rid of the pop-up “BlockUI requires jQuery V1.2.3 or later!”.
The trick is as follows:
1. First open the file manager of your website (it could be through FTP), and go to the folder /public_html/wp-includes/js/jquery. There will be no files jquery.js
2. Open the jquery.js and search for “1.10.1” / “1.10.2” / “1.11.1” / etc (it’s depend jQuery you use, just look the version on the top of the file). Mine is version 1.11.1. Read more…
