I’m having a similar error after the host updated PHP from 5.2.17 to 5.3.21.
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting ')' in /home/user/public_html/wp-content/plugins/widget-logic/widget_logic.php(284) : eval()'d code on line 1
I notice that I had my is_page conditionals like this: is_page(’42’)
I see here that I should not have the apostrophes in there. (Strange that it always worked fine that way, though.
Anyway, on that link, it’s hard to tell but it looks like there’s a space between the ( and the number, like this: is_page( 42 ) Is that correct, or should it be like this: is_page(42) ?
OK, I was able to clear the issue. In case it helps anyone else, it turns out the is_page conditional will work with or without apostrophes, and with our without spaces. It wil not, however, work with just one apostrophe! I had one conditional statement like this: is_page(’42)
The fix is either to add the closing apostrophe or delete the opening one.
