Hi Maciej,

When I try to update a permalink, I have this message below:

Hi @watb,

I adjusted the code in 2.2.8.6 version to prevent this from happening.

Could you try to:
- remove the old instance of plugin
- install it from a fresh copy
All your settings & custom permalinks will be intact.

Best regards,
Maciej

Hi Maciej,

Thanks for your reply.

Unfortunately, that doesn’t fix my issue.
In the wp_options table, “permalink-manager-uris” is always empty and when I try to regenerate the custom permalinks (in WP Tools), I have this message below:
```
 
Warning: array_filter() expects parameter 1 to be array, string given in /usr/local/var/www/blog/www/wp-content/plugins/permalink-manager/includes/core/permalink-manager-uri-functions-post.php on line 531 
```
Thanks again for for help!

Hi @watb,

Could you try to remove the “permalink-manager-uris” in the database? Then, it should be created again as an array.

Best regards,
Maciej
