Hi, Duong
Thank you for your reporting.
Xcache 3.1
Please read readme.txt. This plugin doesn’t support caching plugins. They may cause problems or damage the proper functionality at the worst. I can’t help it, and caching plugins developers can’t help it, either. If you must use caching plugins, I recommend you to use MySQL.
I have an issue when use custom WP_PLUGIN_URL, DISALLOW_FILE_EDIT, DISALLOW_FILE_MODS in wp-config.php.
DISALLOW_FILE_EDIT and DISALLOW_FILE_MODS are features of WordPress, not the plugins’. And they work fine on my environment (WordPress 3.9 beta 2 with sqlite). I recommend you to check if your WordPress installation is complete. I think none of the plugins refer to these two constants in their codes, because there’s nothing to do on the plugin’s side.
As for WP_PLUGIN_URL, this plugin does ignore it. Please use WP_PLUGIN_DIR instead. The reason is that reading files via http has some overheads and causes performance problem. Documents will include this instruction in the next version. Thank you for your advice.
– Show warnning when enable WP debug mode:…
I know this problem on WordPress beta version. This is not because WordPress 3.9 uses mysqli library but because the declaration of one function is changed and PHP doesn’t allow overloading the function like Java or C++. If I change this for 3.9 beta, the released version will give out warning instead. I recommend you to read pdodb.class.php and wp-includes/wp-db.php and compare them, and you’ll know what to do right away.
WordPress 3.9 is not released yet, so they who use it will fix it easily, I guess. But the others who is using a released version now may not be used to programming PHP or may not be able to read warning message properly. I’m unwilling to fix this until WordPress 3.9 is released, though I’m ready to do it.
Very slow when post comments…
Oh… this is the first case. I’ll be glad if you let me know the details of it. What operations did you do? How did you measure the execution time?
If you have time, please check again with the caching plugin deactived and cache data cleaned.
Regards
