A 500 error has occured
500 errors are generally caused by one of the following two problems.
1) A bad entry in the site .htaccess file, if you are the webmaster try logging into your cPanel, and use the file manager to rename your .htaccess file if this fixes the error you should then check the contents of the .htaccess file / roll back any recent changes.
2) A php error / code error also causes a 500 error, you can try enabling 'PHP display_errors' by following this guide Enable Display errors
If after trying both of the above solutions and you are still seeing the 500 error please do contact support
I tried to rename .htaccess and still does not work. There is no problem with the free 500 limit service, but this Standalone Sitemap Generator.
Is there a fix for this error?
