Title: Scan will not complete Last modified: August 21, 2016 --- # Scan will not complete * Resolved [sassafrascal](https://wordpress.org/support/users/sassafrascal/) * (@sassafrascal) * [12 years, 11 months ago](https://wordpress.org/support/topic/scan-will-not-complete/) * Hi there, when I installed WordFence everything worked fine – when I upgraded everything stopped working. (Maybe not due to the upgrade, but timing) It’s constanly getting stuck on scans at “Comparing core WordPress files against originals in repository” and I can’t see any Live Updates anymore – the wheels just keep spinning over and over. * Have I done something in the settings for this to start happening? * [http://wordpress.org/extend/plugins/wordfence/](http://wordpress.org/extend/plugins/wordfence/) Viewing 13 replies - 1 through 13 (of 13 total) * [bcr8tive](https://wordpress.org/support/users/bcr8tive/) * (@bcr8tive) * [12 years, 11 months ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780676) * Same here Sassafrascal – never ends … on and on … til you kill it. * [neilfin](https://wordpress.org/support/users/neilfin/) * (@neilfin) * [12 years, 9 months ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780762) * Same here.

I also reset the scan configurations to the default values. * It’s working fine now. * [fjavier](https://wordpress.org/support/users/fjavier/) * (@fjavier) * [12 years, 9 months ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780768) * Sorry I lied, it should not be running in a permanent manner, here is the sheet from the developer addressing the issue… [](http://www.wordfence.com/docs/frequently-asked-questions/#6) * [bcr8tive](https://wordpress.org/support/users/bcr8tive/) * (@bcr8tive) * [12 years, 9 months ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780769) * fjavier, * Did you mean to attach something? Here is _what_ sheet? * I wish the developers would address this instead of it being in limbo for MONTHS. * Plugin Author [Mark Maunder](https://wordpress.org/support/users/mmaunder/) * (@mmaunder) * [12 years, 8 months ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780774) * Hi Guys, * We offer support on [http://www.wordfence.com](http://www.wordfence.com) in our forums and of course premium support via email. I’m just getting to these forums now so I do apologize for the delay. If anyone’s still having this issue please let me know and I’ll address it. * Regards, * Mark. * [mikeotgaar](https://wordpress.org/support/users/mikeotgaar/) * (@mikeotgaar) * [12 years, 8 months ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780776) * Similar issue with a site running WP 3.6.1 – plugin version 3.8.3 New install on that site, not plugin update. * Scan gets stuck at “Scanned contents of (e.g.) 287 additional files at … per second” Have to force kill to end scan * This extract from error log may be relevant * PHP Warning: Invalid argument supplied for foreach() in /home/****/wp-admin/includes/ plugin.php on line 1290 * PHP Warning: Cannot modify header information – headers already sent by (output started at /home/****/wp-admin/includes/plugin.php:1290) in /home/*****/wp-content/ plugins/wordfence/lib/wfUtils.php on line 507 * Wonder if this is a blank additional line at end of file issue? * Also noted ajax/cron error in server error logs (500 type error) /wp-admin/admin- ajax.php?action=wordfence_doScan&isFork=0&cronKey=9a5bb9437a87ee05bc0d0 and several server 500 errors for /wp-admin/admin-ajax.php * [mikeotgaar](https://wordpress.org/support/users/mikeotgaar/) * (@mikeotgaar) * [12 years, 8 months ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780777) * Partially resolved the scan not completing issue Found some information on the plugin forum that **AskApache caused problems**. I had this plugin installed, but not activated. Deleted it, and added htaccess rule for /wp-admin/admin-ajax. php – allow from all (Not an ideal solution) * Scan now completes when run manually. That’s good enough for me. Still getting the mentioned PHP Warnings in error logs – but I can live with that – WordFence is doing it’s job protecting the site. * [Scott DeLuzio](https://wordpress.org/support/users/scottdeluzio/) * (@scottdeluzio) * [12 years ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780790) * I know this is an older question, but for anyone who is having this issue, check out the WordFence FAQ article on this topic. It might help you out.

So if it’s 90, try setting the option to 75.” * I’ve set the time to 15 seconds. My options page DOES NOT contain an option labeled: ““Maximum execution time for each scan stage” “ * There is a “max_execution_time” but that’s clearly not the same. * [netcentsii](https://wordpress.org/support/users/netcentsii/) * (@netcentsii) * [12 years ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780792) * My scans will not complete, either. I have the latest WordPress version and plugin version installed and activated. * Except one time, every SCAN stalls at about 2200-2400 files and 25-35 MB data analyzed. * I checked the server error-log in the CPANEL as instructed by my host’s Tech Support. It was empty. I checked the php error-log in root directory. No entries in eleven days since the site was created. * One time it completed when I iteratively increased the Options “Maximum memory Wordfence can use” from 256 to 384 MB. It’s still on 384 MB now but the scans won;t complete. I did set the “Maximum execution time for each scan stage” to 15 secs too. * [netcentsii](https://wordpress.org/support/users/netcentsii/) * (@netcentsii) * [12 years ago](https://wordpress.org/support/topic/scan-will-not-complete/#post-3780793) * Where should I upload or submit the server error-log files?
