Yes, the problem is “???”.
I turned off all plugins one by one, and when I turned off “Simple Social Buttons” – the problem disappeared and the text became normal.
It’s when I enable the “Simple Social Buttons” plugin – text in the post excerpts is replaced with “???” characters.
Hi all! Today I encountered the same problem, a client complained that his two sites were hacked. Using FTP, I saw that several third-party plugins had appeared masquerading as WP Task Manager, WP System Cache, etc.
At the root of the site there was also a folder and third-party files.
What is noteworthy is that the malware also replaced sitemap.xml and robots.txt
