Hello,
Thank you so much for the prompt response.
I deleted the backupwordpress plugin just now via the hosting control panel, now I’m able to log in the admin page, and the website is working as well, thanks again for your kindly help.
May I know if I should re-download and install the backupwordpress plugin? If there will be the same issue comes if I do it? Or is there any other plugin which can replace backupwordpress?
Thanks in advance for your response.
