Error has begun associated with cache rebuilding…

    I have had amr-users plugin on my site for a long while now (approx 500 users). All was fine. A couple of months back (exact time unknown) the following error began;

    “A shutdown was triggered, possibly a fatal error was caught. Please note the message below when reporting this.
    Array ( [type] => 1 [message] => Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes) [file] => /var/www/vhosts/iyta.org.nz/httpdocs/wp-includes/wp-db.php [line] => 1778 )”

    I have explored the situation to great length and narrowed down a possible culprit to the auto-caching of the plugin, If I disable all auto caching and only manually rebuild the cache then things seem to run OK (at least for a while!).

    I maintain WP and all other plugins on the site up to date and the site resides on the same shared hosted server it always has.

    I have not yet reinstalled the plugin as I am reluctant to loose all my list and field settings (assuming thats what would happen)

    Any suggestions/advice would be greatly appreciated.

    [My site is iyta.org.nz and the offending list is accessed by ‘Find a Teacher’]

    The ‘culprit’ is not so much the auto cacheing – it is possible that when auto cache runs it may require more memory for some reason – admin side of wp does need more memory. And while you think nothing much has changed, any small thing could have made it hit the threshold and just tipped it over the edge – updated wp, theme or plugin? new user ? more user data ?

    See https://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP

    See the message ?
    Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes)
    That’s 134 MB – try upping it to 256MB

    the plugin the way it is written (historical reasons) is high on memory. See Note 1 on https://wordpress.org/plugins/amr-users/

    Thanks for the quick response Anna-Marie.

    I had in fact increased the memory allocation for WP some time ago for similar behaviour of the plugin and assumed this time around that it was something else. Anyway revisited the memory settings and increased to 256 and things are looking better – will watch and see.

    Thanks again and kudos to you for the most excellent plugin.
