Errore reactivated plugin.

What is the version of php ? An other Guy have the same problem but not me …
??

php version:5.5.8

Very strange as this part has not changed since the last version
You have update php since ?

last time i updated php was 2 or 3 months ago.

And if you try to reinstall 1.5.0 manually ? See the plugin page for old version

Do i just copy the files into the plugin directory? Where is the config information stored?

The config are stored in the database do not worry … Replace the files in the plugin dir

i manually downgraded the plugin and it activated fine. I updated the plugin again and the same error message was given.

Ok … We have at least reproduce the problem … Now I have to understand it ??

Could you try to reactivate the last version by modifying (in line 1374 of core.class.php
static public function get_plugins_data($plugin_file='') {

into
public function get_plugins_data($plugin_file='') {

Sorry to ask but since I do not have the issue …

I have the same issue, same error message.

i changed it but same error.

actually the error is slightly different
Parse error: syntax error, unexpected ‘public’ (T_PUBLIC) in \word\wp-content\plugins\backup-scheduler\core.class.php on line 1374

Whaaaaat ?

Stranger and stranger …

The thing is I do not understand why version 1.5.0 works as it is identical …
