Plugin could not be activated because it triggered a fatal error.

do you have more information on the fatal error ?

the php error log should indicate what exactly was triggering the fatal error, please share that log.

Here you go ^_^:

Fatal error: Uncaught Error: Call to undefined function LiteSpeed\parse_ini_file() in /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/src/base.cls.php:687 Stack trace: #0 /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/src/conf.cls.php(116): LiteSpeed\Base->load_default_vals() #1 /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/src/conf.cls.php(36): LiteSpeed\Conf->_conf_db_init() #2 /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/src/core.cls.php(50): LiteSpeed\Conf->init() #3 /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/src/root.cls.php(220): LiteSpeed\Core->__construct(false) #4 /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/litespeed-cache.php(186): LiteSpeed\Root::cls() #5 /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/litespeed-cache.php(189): run_litespeed_cache() #6 /home/mywebsite/public_html/wp-admin/includes/plugin.php(2389): include_once(‘/home/mywebsite/p…’) #7 /home/mywebsite/public_html/wp-admin/includes/plugin.php(675): plugin_sandbox_scrape(‘litespeed-cache…’) #8 /home/mywebsite/public_html/wp-admin/plugins.php(60): activate_plugin(‘litespeed-cache…’, ‘https://my-web…’, false) #9 {main} thrown in /home/mywebsite/public_html/wp-content/plugins/litespeed-cache/src/base.cls.php on line 687

it looks like your PHP disabled functions parse_ini_file()

this function is needed on activation , please re-enable this function.

figured it out thanks ^_^ guess my host changed it for some reason.. old websites using lite speed and now working without parse_ini_file() will it cause any problems ?

I think it is needed , at least, for first initialization to parse .ini into db conf

thanks
