Enabling js smart cache prevents page from loading.

[DFuentes]

I had been developing some modules for my store's backoffice and suddenly my store won't load. I get the following message:

 

"Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\<my site>\tools\js_minify\jsmin.php on line 309"

 

The number of the line changes, but the message and the file is always the same. If I disable the 'Smart Cache for JavaScript' option in Advanced Parameters > Performance > CCC, the page takes a few secconds but loads.

 

When it is enabled the backoffice works perfectly, it is only a front problem.

 

What could be the cause of this?

What is the theme you are using?  If non-default theme please also supply link of where you obtained the theme.

It's pretty much the default one with different pictures and some extra modules.

to determine if non-prestashop you can toggle, the disable non-prestashop modules and/or overrides 

 

back office-->advanced parms-->performance

 

then see if issue still persists.

 

Note: on chrome you can use ctl+shift+j then click console to see .js errors for example.  |  Also you can enable PrestaShop debug mode (google if you do not know how)

Tried disabling non-prestashop modules and overrides (each one and together), same result.

 

The js console is empty, doesn't even have usual errors, from which I assume it is not loading the page at all.

 

Dev mode is enabled, that's how I got to see the error I mentioned in the first post.

i'm out of ideas, sorry

After reading some websites I increased the server's loading time to allow my site to load and it worked, but still took a few minutes for it to work.

 

In the end I managed to solve it, the problem was xdebug. I changed

[XDebug]
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
xdebug.profiler_append = 0
xdebug.profiler_enable = 1
xdebug.profiler_enable_trigger = 0
xdebug.profiler_output_dir = "C:\xampp\tmp"
xdebug.profiler_output_name = "cachegrind.out.%t-%s"
xdebug.remote_enable = on
xdebug.remote_handler = "dbgp"
xdebug.remote_host = "127.0.0.1"
xdebug.trace_output_dir = "C:\xampp\tmp"

to 

;[XDebug]
;zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
;xdebug.profiler_append = 0
;xdebug.profiler_enable = 1
;xdebug.profiler_enable_trigger = 0
;xdebug.profiler_output_dir = "C:\xampp\tmp"
;xdebug.profiler_output_name = "cachegrind.out.%t-%s"
;xdebug.remote_enable = on
;xdebug.remote_handler = "dbgp"
;xdebug.remote_host = "127.0.0.1"
;xdebug.trace_output_dir = "C:\xampp\tmp" 

in the php.ini and the site went back to normal.

 

It's not the best solution since I have to comment it for the site to be fast and then uncomment it to debug my modules, but it solves my problem.

Any better solutions will be appreciated.
