I cannot log into joomla administrator due to a redirect plug in
We are a not for profit spiritual website that lost our webmaster. Before he left, due to previous hacking issues, he installed a redirect plug in for joomla administrator log in which takes me back to the home page when I use the typical url for administrator. He never shared the new url extension to get me into joomla as administrator before he left. I need a coder or programmer to help find this inside the C Panel and either remove it or give me the url address or extension to let me enter joomla as administrator for my our website. Thank you in advance for your help in this matter.
