[LSCache - WordPress Plugin] .htaccess backups multiple times per minute

[georgetasioulis]

Hello,

I installed the LiteSpeed Cache plugin on one of my WordPress sites and I see that multiple .htaccess backups are generated per minute. After around half an hour I have over 1400 .htaccess backup files.

Any idea why this is happening? I'm running the WordPress LiteSpeed Cache plugin v1.0.9 with LiteSpeed v5.1.7 2-CPU license.

Best regards,
George T.

Hi George,

Do you see any particular differences between each backup?

We changed the code to back up to a different file whenever someone changes a setting. I am not sure why so many are triggered so quickly, so if we can figure out what differences are made, it may be easier to track down the issue.

Hi Kevin,

No there's no difference between the files. As you can see all backups taken at 08:06 for example have the same file size.
And the difference between the first backup files (9916 bytes) and the last ones (9913 bytes) is that I removed some empty lines from the end of the file. Other than that, all 1400+ backup files as well as the original .htaccess file are exactly the same.

I have now disabled the plugin as the htaccess backups wouldn't stop being generated, but I will try it again later tonight when there's less traffic on the site.

 

[KevinFwu]

I see. When it is more time appropriate, could you pm me the ssh & WP admin information for your server? I have a general idea of where the possible source of the problem is, but won't know unless I can reproduce it.

Hi George,

We just released 1.0.9.1 which we hope will include a fix for your problem

If this doesn't fix it, please pm me with temporary access details so we can check into this further.

Regards,
Michael
