Plugin errors after updating wordpress

  • I updated to the latest version of wordpress, before doing this I made sure all plugins were updated.

    After updating I had some problems, the site stated Page not found in the browser

    I renamed the plugins folder and the site came back, out of the 6 plugins I can reinstated only two, any of the other 4 bring the site down.

    I have manually removed each of the plugins and tried to clean with new versions, tried a manual update of wordpress to check if any files corrupt, also attempted a repair and optimisation of the database.

    None of this helps, still trying to activate these plugins brings the site down.

    From my site logs it mentions the following errors:

    PHP Warning:  array_key_exists() expects parameter 2 to be 
array, null given in siteaddress/admin/options-sanitize.php 
on line 79, referer: siteaddress/wp-admin/index.php

    also 

    PHP Fatal error:  Allowed memory size of 41943040 bytes 
exhausted (tried to allocate 1966080 bytes)

    These errors appear numerous times for the plugins in use

    PHP version I have on the server is PHP 5.5

    Any ideas would be really helpful

  • About which plugins you’re talking about? Could be that they don’t support the new WordPress version?

    It could be a problem involving your theme also. Try to use a standard wordpress theme for a sec, and see if the errors continue.

    The first error problem indicates that siteaddress/admin/options-sanitize.php
    on line 79, is not an array. In my opinion your theme or one of your plugins is not able to support new WordPress update.

    Second error you could try to bypass by adding … “define( ‘WP_MEMORY_LIMIT’, ‘256M’ );” in your WP-Config.

    Login to your Cpanel or DirectAdmin and try to change to PHP7.

    “PHP Warning: array_key_exists() expects parameter 2 to be
    array, null given in siteaddress/admin/options-sanitize.php
    on line 79, referer: siteaddress/wp-admin/index.php”

    Could you paste line 79 here in the forum one time?

    Hi Djenci
    The plugins I have in use that break the site are:

    Contact form 7
    mappress
    simple 301 redirects
    wordpress seo (yoast)
    wp-spamfree

    the only plugins that work and do not break the site are:
    advanced custom fields
    acf repeater

    line 79 for options-sanitize is:
    if ( array_key_exists( $input, $option['options'] ) ) {

    it is part of this function …

    /* Check that the key value sent is valid */

function of_sanitize_enum( $input, $option ) {
	$output = '';
	if ( array_key_exists( $input, $option['options'] ) ) {
		$output = $input;
	}
	return $output;
}

    Contact form 7 and Yoast work with the latest WP without any problems. So they, on they own, are not the cause.

    I switched over to a default theme and all working fine.

    I added the line for more memory in the wp-config file.

    Asked host to upgrade version of php and allocate more memory and cpu execution time.

    All working well now and able to get plugins running again.

    Thanks for taking the time to help ??
