Parse error: syntax error

Hi
while working on my website, the site suddenly shot down with a syntax error: Parse error: syntax error, unexpected ‘avia_framework’ (T_STRING) in /var/www/www.ikkeenpind.dk/www/wp-content/themes/flashlight/includes/helper-slideshow.php on line 230

I have tried to replace line 230 with the correct one, tried to replace the helper-slideshow.php, and tried to update the whole theme, but non of this seems to fix the problem.

I installed a new plugin just before the error cured but looking though my plugin folder now I cant find the plugin. What can I do to fix this problem?
