There is no WordPress 7.3, perhaps you mean PHP 7.3?
Try asking your webhost support about PHP update
Yes I wanted to write PHP 7.3. I have already talked with the host and they answered me that they updated php to 7.3 after the message appeared. Now i have to find a solution because i cannot login to the website.
