Recently updated to PHP 7.2 (from 7.0) and since can’T open documents in Collabora anymore. The click on such a document in the browser UI responds with a HTTP code 500 and the server log print this message:
[error] [pid 10510] PHP Fatal error: Cannot declare class GuzzleHttp\\Exception\\RequestException, because the name is already in use in /var/www/nextcloud/paragon/3rdparty/guzzlehttp/guzzle/src/Exception/RequestException.php on line 0
The same configuration worked in PHP 7.0 so I guess that 7.2 is more strict somewhere but I haven’t found a second instance of
GuzzleHttp\\Exception\\RequestException anywhere in the code base.
Any ideas what could be causing this?
