Strance error-messages on top of pages

[PE1PQX]

Hi everyone,

On top of every page I see an annoying error-message:

Strict Standards: Only variables should be assigned by reference in /var/www/vhosts/pe1pqx.eu/httpdocs/plugins/content/phocagalleryslideshow/phocagalleryslideshow.php on line 37

Strict Standards: Only variables should be assigned by reference in /var/www/vhosts/pe1pqx.eu/httpdocs/plugins/content/phocagalleryslideshow/phocagalleryslideshow.php on line 38

How do I get rid of it?? I can't find is in the back-end of Joomla 3.4.1.
used template: based on Beez3, and slightly altered in the code itself.
GallerySlideshow plugin is not installed...

Thanks!
André, PE1PQX

Hi,

Will check, than you so far.

Edit:
Editing php.ini did not solve the problem. Changing Error Reporting parameter in Joomla! Global Configuration did solve it.

Thank you for your answer!
