Parse error: syntax error, phpbb3 forum index

I'm testing a phpbb3 forum with custom themes/templates and modifications, and I'm getting this error on my home page:

You can see it for yourself here:

This is the forumlist_body.html file in my template folder:

Code (markup):

I'm sure this is a simple problem... At least I hope it is. Thoughts?

 

Holy CRAP, phpbb hasn't gotten any better since last time I played with it. Makes WordPress look like the definition of well-constructed code.
However, at a quick glance (on my phone) I can't really see any errors in the code you posted. However, the error might not actually be in that file. It depends on what is being included etc which will skew the line count somewhat.

 

If the problem isn't in that file, is there any way I can figure out how the files may be combined with one another?

Something else I don't understand is how the "forumlist_body.html" file becomes 'tpl_orbital_forumlist_body.html.php", which doesn't seem to exist as far as I can see. And definitely this directory does not appear for me on my site: /home/u753364033/public_html/cache/

Does php create these things and combine coding files into single files in the cache?

And one more question... Can I quickly browse all the other code files in my template folder without having to open them all individually and look for problems? Or can I look at the files that might be combined in the php?

 

It's adding the template name or something to the front of the file name, I'm guessing, and appending php, so as to parse it via the php parser - the /home/u.../public_html folder is probably your path to the root folder of your website.
You can easily open all the template files in an editor, and search through all of them, but it will be very hard to search for your problem (unless you are an expert in regular expressions)

 

Well I made some progress ....

This cache directory does indeed exist, I just didn't notice it because the "root" it makes mention of is deeper than I'm allowed to see apparently.

I found the file "tpl_orbital_forumlist_body.html.php", which is generated whenever I try to view the board index of the CA Orbital style. And it does have an out-of-place "}", which I can delete. There are two new problems: (1) whenever I clear the cache and this page is regenerated, it contains the same error; (2) if I remove this error manually from the cached page, there's another error of the same type, and so on, until the board finally loads but does not show any forums.

This is the tpl_orbital_forumlist_body.html.php page as it's being generated:

<?php if (!defined('IN_PHPBB')) exit; $_forumrow_count = (isset($this->_tpldata['forumrow'])) ? sizeof($this->_tpldata['forumrow']) : 0;if ($_forumrow_count) {for ($_forumrow_i = 0; $_forumrow_i < $_forumrow_count; ++$_forumrow_i){$_forumrow_val = &$this->_tpldata['forumrow'][$_forumrow_i]; ?>

Code (markup):

You can see the extra "}" on line 105. There are other extra "}" symbols too. I don't know much about php but I'm guessing that this file is being generated by some other code automatically, and somewhere there is a bad code making it generate this extra crap. Am I wrong here?

 

Nope, that is quite correct. The cached file is generated, with the error, and changing that cached page (or deleting it) won't help, since it will just recreate the page again at a later stage.
Unfortunately, the code for PHPBB is crap - pure and utter crap - I've been playing around with it before, and it's a complete pain in the ass to figure out where errors show up from.
If you've changed the core files (adding plugins or similar), I would suggest just reinstalling the board (just reupload the core files), then add plugins one by one, checking after each one to see if there are errors again. Also, maybe remove the template (go back to default, or something), then reinstall that.
