Prestashop has crashed! Please help!

Hello,

 

My prestashop installation has crashed. I only get a blank screen and can't access the backend. 

This happened a few hours ago, and I thought it might be due to a module I had just installed (a free accessories module from presto-changeo). I manually deleted the module folder via FTP, and the site appeared to be working again, until I tried to run a backup using the PrestaBACKUP module, then it crashed again. I got this error on the backend:

 

[PrestaShop] Fatal error in module smarty_internal_write_file:
Uncaught exception 'SmartyException' with message 'unable to write file /home/mysite/public_html/cache/smarty/compile/ed/f3/4d/wrt545bfd205ebd82.10510655' in /home/mysite/public_html/tools/smarty/sysplugins/smarty_internal_write_file.php:44 Stack trace: #0 /home/mysite/public_html/tools/smarty/sysplugins/smarty_internal_template.php(201): Smarty_Internal_Write_File::writeFile('/home/mysite/p...', 'compileTemplateSource() #2 /home/mysite/public_html/classes/controller/AdminController.php(1936): Smarty_Internal_TemplateBase->fetch('controllers/mod...') #3 /home/mysite/public_html/controllers/admin/AdminModulesController.php(1259): AdminControllerCore->initModal() #4 /home/mysite/public_html/classes/controller/AdminController.php(2337): AdminModulesControllerCore->initModal() #5 /home/mysite/public_html/classes/controller/Controller.php(163): AdminCont

 

I do not seem to be having any server issues and I am able to access other sites on the server, and a blog site that is hosted in a subfolder of the prestashop installation. I can also access images stored in the prestashop root folder, but any other pages return a blank screen with no source code (not a 404 error).

 

Please help. I took a backup of the entire server last night, but I have done quite a bit of work today entering in products, and I do not want to lose it.

 

Thanks.

Problem solved. It had nothing to do with Prestashop. I ran out of disk space. Increasing the quota in WHM fixed the problem.
