Sorry abou this yet another issue - I think I've broke my site again. I was attempting to edit the theme, but when I reloaded my site, this popped up:
Fatal error: Uncaught exception 'SmartyException' with message 'unable to write file /home/wallie12/public_html/templates/compile/wrt53024c1dbd2e70.20765048' in /home/wallie12/public_html/inc/smarty/sysplugins/smarty_internal_write_file.php:44 Stack trace: #0 /home/wallie12/public_html/inc/smarty/sysplugins/smarty_internal_template.php(201): Smarty_Internal_Write_File::writeFile('/home/wallie12/...', '<?php /* Smarty...', Object(Template)) #1 /home/wallie12/public_html/inc/smarty/sysplugins/smarty_internal_templatebase.php(164): Smarty_Internal_Template->compileTemplateSource() #2 /home/wallie12/public_html/inc/smarty/sysplugins/smarty_internal_templatebase.php(374): Smarty_Internal_TemplateBase->fetch('template.tpl', NULL, NULL, NULL, true) #3 /home/wallie12/public_html/classes/class_frame.php(226): Smarty_Internal_TemplateBase->display('template.tpl') #4 /home/wallie12/public_html/classes/class_mysidia.php(449): Frame->render() #5 /home/wallie12/public_html/index.php(86): Mysidia->output() #6 /home/wallie12/public_html/ in /home/wallie12/public_html/inc/smarty/sysplugins/smarty_internal_write_file.php on line 44
