I’ve been trying to debug a weird bug on Drupal 7 for awhile. It happens randomly on my site as it’s hard to reproduce. I’m able to finally get ddebug_backtrace() to run when the error happens. The error breaks all of my views on the site when it happens and throws the following error:
Warning: include(/home/xxx/public_html/.tpl.php): failed to open stream: No such file or directory in theme_render_template() (line 1534 of /home/xxx/public_html/includes/theme.inc).
It’s complaining that theme_render_template() can’t find a template file as the variable given to the function is just .tpl.php.
I’m able to insert an if statement when this happens within that function as this:
if($template_file == '.tpl.php') { ddebug_backtrace(); print_r('<pre>xxxx'); print_r('TEMPLATE FILE: '); print_r($template_file); print_r('</pre>'); } I’m able to get the debug output in krumo as shown below. I’m not exactly sure what I should be looking for. I just understand that each numbered line represents where that function was called within that order. But what I’m trying to look for is a blank variable of some sort which makes it output .tpl.php to give such an error.
Judging from the output, the culprit is the Views module, but I’m not sure where. What should I be looking for exactly?
