To fix this issue, you’ll need to access your website through FTP. Depending on your browser, you may need to access the website using an FTP client to fix the problem. First, you’ll want to open the wp-content folder and then go to the themes folder. To do this, right-click the theme folder. Once you’ve done this, you’ll want to try to log in again. If this doesn’t solve the problem, contact the theme provider.
If the error still persists, try refreshing your browser or clearing your browser’s cache. In addition, make sure you have cookies enabled. The problem can also be caused by a corrupted login file. You can delete this by clicking the three-dotted icon in your browser’s settings. Then, try using the same method for your WordPress login again. If none of these steps work, contact a WordPress maintenance service. There are also other ways to fix the problem.
