php parse error and fatal error

Hello, My web page is down and I receive the following errors.

Code: Select all

<b>Parse error</b>:  syntax error, unexpected '||' (T_BOOLEAN_OR) in <b>/homepages/19/d110054608/htdocs/avios2/wp-content/themes/MeetGavernWP/gavern/helpers/helpers.layout.php(792) : runtime-created function</b> on line <b>1</b><br />
<br />
<b>Fatal error</b>:  Function name must be a string in <b>/homepages/19/d110054608/htdocs/avios2/wp-content/themes/MeetGavernWP/gavern/helpers/helpers.layout.php</b> on line <b>794</b><br />

I know you have fixed this in the past, but I was not able to follow how you fixed this issue.
My web page is http://www.avios.org
I should also note this is MeetGavern theme, I purchased a theme just to ask this question.

Could you please provide me with a back-end and FTP access to your website via PM (click the “Private Message” text underneath my avatar) so that I may analyze it?

Are you using the latest version of MeetGavernWP?

Your theme version is Version: 1.9.3, the latest version of MeetGavernWP is 1.15.

Please upgrade your theme and the issues should be gone.

I'm sorry to say, this did not fix the issue. I still have an error on the front page.
