It's a warning that I think can be safely ignored.

Open the file mentioned in error message and find in line 161 html_entity_decode() function. Make sure it's properly called.

The same thing happened to me, the error is not seen with php5.5

Did you solve the error?

I just moved back to 5.5 until I find a solution, different people told me a different answer but nothing explicit my website is live, and I don't want to mess, I even don't mind paying someone for offering me the solution.

Interesting. "UTF-8" as the third parameter to the call (not the second, as some examples in the PHP manual give) is supposed to be supported. If it accepts "utf-8" instead, I'd say that's a PHP bug (which may have been fixed in recent versions), and easily worked around. It may also be worth checking if the input string is using any invalid HTML entity names, although the error message doesn't quite sound like that's the case.

Fixed the Warning issue PHP 5.5

Thanks Thanks

Well, it's always better to fix a problem, than just ignoring it, and then need
a Custom Mod, to shrink the error log file at a regular pace, just to keep the
software from one day run out of Server Memory ...
At least from a swiss point of view. But we always have been less tolerant than
others, when it comes to 'minor' details ...

The root cause of the problem is actually the semicolon on the end of each line in the php.ini file.

Remove the semicolon frome the end of the line in both php.ini files. You may also need to edit the setting in the Editor Mode tab of the cPanel MultiPHP INI Editor if your hosting uses it. Also check .htaccess in case you php.ini settings have been imported there.
