Rema, please provide a site URL. Additionally try clearing your browser cache by pressing CTRL + F5, if that doesn't workyou can search Google for instruction on how to do this - it can change depending on the browser. If none of the above works, as Xayaan has said above try removing custom scripts from the website if there are any. Apart from that a site URL will aid in further analysis of these issues.
