Just got this security error

Error details:
Some files have not passed the integrity check. Further information on how to resolve this issue can be found in the documentation. ([List of invalid files…]

Does that mean we cannot change .htaccess file and also cannot add ssl related files inside .well-known folder.

Unfortunately you’ve completely ignored the issue ticket and didn’t provide any valuable information about your environment system, software versions, etc., etc. so that I cannot answer your question. Please try to use the search function of this forum first, because questions concerning .well-known folders have already been asked and answered in the past.

No worries Sir and thanks for the reply. I solved that issue. Actually that happened after an update so I wont be updating it anymore and if any php security issue is there I will handle it myself as I just completed an advanced php course.
