Trouble shooting: PHP Parse error: syntax error, unexpected string content "toggl"

Since updating plugins, I can't access Grav's admin page.
Logs show this error:
PHP Parse error: syntax error, unexpected string content "toggl"

Any idea about the origin and way to correct will be welcome!

This can't be a full error. It should also contain the file and the line

You're right:

PHP Parse error: syntax error, unexpected string content "toggl" in /srv/data/web/vhosts/www.apsed.fr/htdocs/cache/compiled/files/09a1ab1b3abd2edc10ef0debd57bc4cb.yaml.php on line 89

@apSed, A link to a non-existing file doesn't really help. Those files in folder /cache are fleeting.

Suggestions:

• Copy/past the relevant lines from the *.yaml.php file, instead of showing a link.
• And/or, if the error is logged into/logs/grav.log, copy/paste relevant parts from that file.
