After doing a migration (url and server) buapos.com forosbuap.mx to some sites stopped working with this error:

Fatal error: Can not use string offset as an array in / home / Mius / public_html / wp-includes / capabilities.php on line 112

This only happens on some sites, for example https://noticias.buapos.com works properly, but https://iklae.buapos.com/ not work.

If visiting as a guest, the site can be displayed to the header, but as administrator the site does not show anything.

Try disabling the plugins without success.

The only change was in the url of each site.
