I tried to delete the last plugin i installed… The same problem!
Have you tried:
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
– re-uploading all files & folders – except the wp-content folder and wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
What is the root .htaccess files? that I should keep.
It is a file created in your root WordPress folder when you use custom permalinks.
Sorry I am a bit new to all of this! So I see the wp-content and the wp-config.php that I should not replace. (I tried replacing the wp-admin also) But I can see the root .htaccess files or file! I didn’t understand what do you mean exactly. is it just enough to only re-upload the wp-includes??
is it just enough to only re-upload the wp-includes?
No. You need to re-upload a complete set of WordPress files & folders. Were you using custom permalinks previously? Is your FTP client configured to show all files?
yea I am using the FTP and I can see the all files.
Oh FINALLY!
The problem was because of the plugin “Seamless Donations”!
Thank you very much for your help. But the thing is that I didn’t install any update for this plugin! All for sudden it is showing a conflict.
Thank you a lot.
if you can refer me to a good plugin for donations if you know any!
