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.
3. Change “1.11.1” into “1.9” and save the file.
4. Refresh your website and it solved.
