fashe theme problem

hello. every time i go to do anything like add a picture or change the font or change a collection i get this little rd pop up in the corner. no idea what it means or what to do. i can change fonts or add anything.

Hello there,

I hope you are doing well today.

That is strange, please contact your hosting provider and have them increase your server resources such as the max execution time and the php memory limit.

Best Regards,
