Conditional errors after upgrading to EE 2.9 (just a helpful hand)

Question

The upgrade we did last night from 2.8.1. to 2.9 seemed OK. However we only tested the back-end so far!

While running the front-end we're getting these errors messages on all pages…

Error

You have an invalid conditional in your template. Please review your conditionals for an unclosed string, invalid operators, a missing }, or a missing {/if}.

Lexer State: if: is a reserved prefix.

Of course we're focussed on finding incorrect conditional errors and couldn't find any! Checked 50+ templates. Close to giving up we found the issues caused by a missing } in a script in our HTML footer…..

Answer 1

Yes the syntax seems more strictly enforced...I've found a number of missing } and / in my code, even an entirely missing {/if}. I just remove big chunks from my template to quickly narrow it down to smaller areas...it's usually not hard from there.

Answer 2

I also found this case:

{exp:channel:entries channel="resources" status="open" url_title="{last_segment}" limit="1" disable="member_data|trackbacks|pagination" track_views="one"}
{exp:ifelse parse="inward"}
     {if xxx}


     {/if}
{/exp:channel:entries}
{/exp:ifelse}

did not work, but

{exp:channel:entries channel="resources" status="open" url_title="{last_segment}" limit="1" disable="member_data|trackbacks|pagination" track_views="one"}
{exp:ifelse parse="inward"}

     {if xxx}

     {/if} 

{/exp:ifelse}
{/exp:channel:entries}

did. Note the order of the channel entries tag and the closing IfElse tag in relation to the opening tags.
