Corrupt .php page cannot be edited

Hello,

On a shared hosting with PHP version 5.6 I have many .htm pages

Trying to create a new page with the same name in .php, SURPRISE, the spot is already "occupied" and unassignable with an empty page but rich in CSS

:root zeus-ad, :root span[id^="ezoic-pub-ad-placeholder-"], :root ins.adsbygoogle[data-ad-slot], :root guj-ad, :root gpt-ad, :root div[id^="zergnet-widget"], :root div[id^="vuukle-ad-"], :root div[id^="taboola-stream-"], :root div[id^="sticky_ad_"], :root div[id^="pa_sticky_ad_box_middle_"]

etc.

see for yourself:

thanks for your insights

Hello,

I don't quite understand your problem. You made a site "hand-made" and you are probably the author of what's there.

Hello,

What do you mean by:

wanting to create a new page with the same name in .php SURPRISE the space is already "occupied" and unusable with an empty page but rich in CSS

Page name already existing at OVH.

to check with the application FILEZILLA in mode *** SFTP ***:
See in my guide the paragraph: E - Installation du logiciel FTP FILEZILLA

Indeed, and that's on me, the PHP page wasn't functional and the spammy CSS seems to be coming from the browser rather than the server.

Thank you for your quick responses.
