Title: 500 Internal Server Error – php problems Last modified: August 18, 2016 --- # 500 Internal Server Error – php problems * Resolved [zeroblade](https://wordpress.org/support/users/zeroblade/) * (@zeroblade) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/) * Every time I try to even access my site ([http://zeroblade.whitecosmos.net/blog/](http://zeroblade.whitecosmos.net/blog/)), it only shows the 500 Internal Error Screen. I’ve checked the other sites hosted on the same server and they seem to be working perfectly; this is the only part of the site that’s had this problem. After checking error_log, it had this to say: * “May-2007 03:57:40] PHP Fatal error: require() [[function.require](https://wordpress.org/support/topic/500-internal-server-error-php-problems/function.require?output_format=md)]: Failed opening required ‘/home/whitsnet/public_html/zeroblade/blog/wp-content/ advanced-cache.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/ whitsnet/public_html/zeroblade/blog/wp-settings.php on line 84″ * Can anyone tell me how to solve this issue? I know nothing of php so I don’t really understand how to fix this.

Someone checked their error logs! Trying to give me another heart attack?!?!?! * Sorry but that just doesn’t happen all that often around here. 🙂 * Thread Starter [zeroblade](https://wordpress.org/support/users/zeroblade/) * (@zeroblade) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588167) * Yeah, it’s the damnedest thing; the readme says to create a symbolic link from wp-content/advanced-cache.php to wp-content/plugins/wp-cache/wp-cache-phase1. php, yet advanced-cache.php doesn’t even exist. That and I haven’t the slightest clue on how to create the said link. * [whooami](https://wordpress.org/support/users/whooami/) * (@whooami) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588171) * _Yeah, it’s the damnedest thing; the readme says to create a symbolic link from wp-content/advanced-cache.php to wp-content/plugins/wp-cache/wp-cache-phase1. php, yet advanced-cache.php doesn’t even exist._ * Thats WHY you have to create the symbolic link. wp-cache-phase1.php **does** exist. * You create symbolic links by using telnet or SSH to access where you site is hosted. Once youve done that you can perform what are called shell commands. If you dont have telnet or SSH access then maybe ask your host nicely to do it for you. * **Create a symbolic link from wp-content/advanced-cache.php to wp-content/plugins/ wp-cache/wp-cache-phase1.php.** * _ln -s wp-content/plugins/wp-cache/wp-cache-phase1.php wp-content/advanced-cache. php _ * ^^ Once you have shell access, ^^^^^^^^ thats what you do. * [ccoupe](https://wordpress.org/support/users/ccoupe/) * (@ccoupe) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588174) * Step away from the cache Citizen. If you have shell access, the target will be created. Back up out of the rabbit hole. Do you really need that plugin? Are you sure? * [whooami](https://wordpress.org/support/users/whooami/) * (@whooami) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588175) * well admittedly, this guy, the author, could have put together a script to do that. Ive toyed with doing it for a while. It wouldnt be that difficult. But i dont use the plugin, and I dont get enough donations 😛 * [ccoupe](https://wordpress.org/support/users/ccoupe/) * (@ccoupe) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588179) * [OT:] I run a lovely anit-spam plugin that stops spam dead without all the wonders of blacklists and word lists and too late now, mark it as spam. Is it packaged into something regular people can use? No. Did i package it up for him and write some install instructions? I probably did. Did the author care? Sort of, but the fun for him was ‘proof of concept’. * Every plugin and every theme is the same way. Might work next year, might not. The author might care. They might not. * Thread Starter [zeroblade](https://wordpress.org/support/users/zeroblade/) * (@zeroblade) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588185) * To be honest, this happened to me before too, but I removed “define(‘WP_CACHE’, true);” from wp-config.php and promptly deleted the plugin. It hasn’t troubled me since until now. A friend’s lending me the space, so I’ll ask if he can have his host fix the problem. * Thread Starter [zeroblade](https://wordpress.org/support/users/zeroblade/) * (@zeroblade) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588225) * I apologize for the double post, but I’ve been able to contact my friend; he says he’s just experience the same thing as well, so I can assume now that it’s server issues. Thanks for the help and I apologize for the inconvenience. * [whooami](https://wordpress.org/support/users/whooami/) * (@whooami) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588228) * zeroblade, if you dont have shell access I can reccomend a alternate solution…( if you come back) * Thread Starter [zeroblade](https://wordpress.org/support/users/zeroblade/) * (@zeroblade) * [18 years, 11 months ago](https://wordpress.org/support/topic/500-internal-server-error-php-problems/#post-588252) * Oh, what is it? I’d be rather interested once I learn how php and MySQL.
