Fatal error:

Hello @developeresfera

Thanks for reaching out about your XML sitemap. This error is typically caused when the resources required to generate the sitemap are not available or the request is timing out due to the resource restrictions of the server environment. We would first recommend ensuring that the PHP settings for both?max_execution_time?and?memory_limit?are set to a high enough value in the PHP environment. This setting is typically controlled by editing the values in a php.ini file such as in the following example: max_execution_time = 300 memory_limit = 256M
If you are unsure how to change these settings in php.ini, we recommend contacting your hosting provider for additional assistance.
