mobile site open display as below:
0 - syntax error, unexpected 'as' (T_AS), expecting variable (T_VARIABLE) or '{' or '$'

What problem?
Any one can help me out?Thank you!

Could you check error_log file (there should be more details about the error, in particular filename and line number where this error is found)?

Methods with the same name as their class will not be constructors in a future version of PHP; plgSystemiJoomlaNews has a deprecated constructor in /public_html/plugins/system/ijoomlanews/ijoomlanews.php on line 16

I use PHP7.
What's wrong?

All was done!
Thank you very much!
Mysef fault!
