[Plugin: W3 Total Cache] Warning: Cannot modify header information – header
Hi – thanks for plugin but unfortunately it ruined quite a lot in our blog. I installed it and then only got error messages like this:
Warning: Cannot modify header information – headers already sent by (output started at wp-config.php:1) in wp-includes/pluggable.php on line 866
for example. I then googled and was advised to remove the plugin – which I tried but did not succeed fully – thus deleted other files and folders manually like suggested further. I can now login again and mostly it works fine – but despite thinking I removed most files (all the ones I could find) from the plugin but still get this error message above here and there (e.g. after I update a plugin)
Any help how to finally fix this issue would be greatly appreciated!
