I want to know that where the plugins settings data saved in server? Means, when we change any plugin settings (e.g. For simple captcha, it is settings as-> use number, user alpha, captcha color etc), then in which file or database , these settings are saved.
All settings of the Plugin will be saved in the db.
Your Plugin can choose which table they wanted to store the setting into. Check the source code of your Plugin.
get_options()
, then it will stored in the wp_options
tableget_post_meta()
, then it will be stored in the wp_postmeta
tableget_comment_meta()
, then it will be stored in the wp_commentmeta
tableYour Plugin might also have created its own table to store the settings.
